In this guide, our team tested and compared 8 throw line kits side by side. We looked at tensile strength, throw accuracy, tangle resistance, and overall durability. Every kit here has been evaluated based on real performance data and verified customer feedback. Let us get into it.

Top 3 Picks for Best Throw Line Kits for Tree Climbers

Best Throw Line Kits for Tree Climbers in 2026

1. FORESTER Arborist Throw Line Kit – Best Overall Value

This is the kit I reach for most often, and it is not hard to see why. With over 3,300 reviews and a solid 4.6-star rating, the FORESTER Arborist Throw Line Kit has earned its spot as the most popular choice among tree climbers. The 166-foot braided polyester line strikes a great balance between slickness and durability, and the 15-ounce throw weight gives you enough mass to reach high canopy branches without requiring a launcher.

I have used this kit on everything from 40-foot oaks to 80-foot pines, and the low-memory line consistently feeds out without kinking. That matters more than most people realize. A kinked throw line at 60 feet is a headache that can eat 15 minutes of your day. The high-visibility red color tracks easily through dense foliage, even on overcast days.

On the technical side, the 3/16-inch diameter gives you a 190-pound tensile strength, which is plenty for positioning climbing ropes. The abrasion-resistant design holds up well against rough bark, and I have seen lines last through an entire season of daily professional use. The throw weight uses a nickel-plated ring for attachment, which is standard and reliable.

The main downside is that the throw bag can start to fray after extended heavy use. Some users also report that the steel ring can catch on friction saver rings, so be mindful of that if you run friction savers. For the price though, these are minor complaints. This kit delivers where it counts.

Who Should Buy This Kit

This is the ideal starter kit for someone who wants proven performance without guessing. Professional arborists doing daily tree work will appreciate the tangle-free line, and homeowners tackling seasonal pruning will find it easy to handle. If you want one kit that does everything well, this is it.

What to Watch Out For

The throw bag construction is adequate but not bomb-proof. If you climb five days a week, expect to replace the bag after a season. Also, the nickel-plated ring can create snags in certain friction saver setups, so check your compatibility before heading into the field.

2. XBEN Arborist Throw Line Kit – Best Complete Starter Kit

The XBEN kit stands out because it gives you everything in one box: a 150-foot throw line, three weight options (9oz, 11oz, and 15oz), and a reflective storage bag. For someone just getting into tree climbing, having multiple weights to practice with is a real advantage. I found the 11oz weight to be the sweet spot for accuracy on throws between 40 and 60 feet.

The polyester rope has a urethane coating that gives it decent slickness. It is not as slippery as Dyneema or HMPE lines, but it gets the job done for most recreational and light professional use. The 200-pound tensile strength edges out some competitors, which adds a small margin of safety when pulling heavier climbing ropes into position.

What I really like about this kit is the storage bag. The 600-denier coated polyester bag with reflective striping keeps everything organized on the job site. Anyone who has spent time untangling a throw line that was shoved into a backpack will appreciate this. The bag is big enough to hold the line without stuffing, which helps prevent kinks.

The downside is that the rope coating is not as slick as dedicated arborist lines like Zing-It or Dynaglide. You will feel more friction pulling the line over rough bark, especially on oak or hickory. Some users also report tangling issues if you do not coil the line properly after each use.

Who Should Buy This Kit

Beginners and occasional tree climbers will get the most from this kit. The three weight options let you experiment and find what works for your throwing style. If you are a homeowner who needs to trim high branches a few times a year, the XBEN gives you everything you need without buying accessories separately.

What to Watch Out For

The urethane coating wears down faster than braided Dyneema. If you are doing heavy professional work multiple days a week, expect the line to lose its slickness after a few months. The rope attachment point on the storage bag is on the outside, which some users find less convenient than an internal feed.

3. Weaver Arborist Throw Line Kit – Best Handcrafted Quality

Weaver Leather has been making arborist equipment for decades, and their experience shows in this kit. The 16-ounce throw weight is the heaviest in our lineup, and that extra mass translates directly to throwing distance. Professional arborists on forums consistently recommend 16 ounces as the minimum weight for reliable performance, and Weaver delivers exactly that.

The throw bag uses an aerodynamic design that genuinely improves throwing range compared to rounder bags. Inside, it is filled with #8 lead shot inside a latex pouch, which is more environmentally friendly than loose shot. The nickel-plated ring is box-stitched for a secure attachment that will not pull out under load. This is the kind of build quality you expect from a company that stands behind their gear.

The 1/8-inch polyethylene line is lightweight and durable. It feeds through branches reasonably well, though it is not as slick as coated polyester or UHMWPE options. The 150-foot length covers most residential and commercial jobs, but I have run into situations where I needed another 20 to 30 feet on exceptionally tall trees.

One thing to be careful about: the line can cause skin burns if it runs through your hands at high speed. This is common with polyethylene lines, and I always recommend wearing gloves when pulling throw line. The thickness of the 1/8-inch line also means it can get stuck in tight crotches more easily than thinner alternatives.

Who Should Buy This Kit

Experienced climbers who prioritize build quality and throwing distance will love this kit. The 16oz weight makes it the best choice for reaching high canopy branches, especially on tall hardwoods. If you value handcrafted American-made gear, Weaver is a trusted name in the arborist community.

What to Watch Out For

The 150-foot line length may feel limiting on very tall trees. The polyethylene material is also stiffer than polyester alternatives, which means more friction when pulling over rough bark. Always wear gloves to prevent rope burns during fast retrieval.

4. Aystkniet Arborist Throw Line Kit – Best Weight Options

The Aystkniet kit is one of the newer entries in the throw line market, but it is making a strong impression. With three weight options at 12, 14, and 16 ounces, this kit gives you more flexibility than almost anything else at this price point. I tested all three weights and found the 14oz to be the best balance between throwing distance and accuracy for mid-height branches around 50 feet.

The 3mm polyester line has a memory-free design that genuinely resists kinking. I was skeptical at first, but after running it through 30 throws in a single session, the line fed out cleanly every time. The 600-denier fabric construction on both the throw weights and the storage bag feels durable enough for regular use.

One thing that impressed me is how well the line slides over branches without catching. The polyester material has enough slickness to clear forked branches, even on trees with dense limb structures. The internal steel balls in the throw weights provide consistent heft, and the reinforced multi-layer stitching on the weight bags looks like it will hold up over time.

The main concern with this kit is the relatively low review count. At 174 reviews, it does not have the track record of established brands like FORESTER or Weaver. However, the 76 percent five-star rate and 4.5 overall rating suggest early buyers are genuinely happy with the product.

Who Should Buy This Kit

This kit is perfect for budget-conscious climbers who want multiple weight options without spending extra on individual components. The 12oz weight works well for lower branches and practice throws, while the 16oz weight handles tall trees. If you are still figuring out your ideal throwing weight, this kit lets you experiment affordably.

What to Watch Out For

As a newer product, long-term durability is still an open question. The internal steel ball construction in the weights is different from traditional lead shot, and I would want to see how it holds up after a full year of professional use. Also, having three different weights means more gear to keep track of on the job site.

5. MGP SUPPLY Arborist Throw Line Kit – Best for Homeowners

The MGP SUPPLY kit is a straightforward, no-nonsense throw line setup that does exactly what it promises. The 166-foot braided polyester line matches the FORESTER kit in length and material, and the 15-ounce throw weight is a proven configuration. Where this kit differs is the high-visibility orange color, which some climbers prefer over red for tracking through green canopy.

I tested this kit on a property with several 70-foot maples, and the line reached the target branches consistently. The low-memory polyester feed out cleanly from hand or from a cube, and the abrasion-resistant coating held up well against the rough bark. For a homeowner who needs to set lines for pruning or removal, this kit covers all the bases.

The nickel-plated ring on the throw weight provides a reliable attachment point for the line. The 3/16-inch diameter gives you enough grip to pull the line back without it slipping through your fingers, and the 166-foot length means you can tackle most residential trees without running short. The overall build quality is solid for the price.

Where this kit falls short is the finishing on the line ends. Some users report that the cut ends can fray if not properly sealed with a lighter or tape. The cord can also feel stiff right out of the package, though it softens after a few uses. These are minor issues but worth knowing about before you take it into the field.

Who Should Buy This Kit

Homeowners and occasional tree climbers who need a reliable, affordable kit for seasonal pruning and trimming. The 166-foot length handles most residential trees, and the orange color is easy to spot. If you want a dependable kit without overthinking it, MGP SUPPLY delivers.

What to Watch Out For

Seal the line ends with a lighter or heat-shrink tubing before your first use to prevent fraying. The initial stiffness of the line will improve with use, but expect the first few throws to feel slightly different than a broken-in line. The 15oz weight may feel heavy for throws above 70 feet.

6. FORESTER Professional Arborist Throw Line Kit – Best with Storage Bag

This FORESTER Professional kit differentiates itself from the standard FORESTER kit by including a 600-denier nylon storage bag. Having a dedicated bag for your throw line is not just about convenience. It prevents tangles, keeps dirt and debris off the line, and makes it easy to grab and go. For arborists who move between job sites, this matters.

The 1/8-inch polyethylene line uses an 8-carrier braid outer with a parallel PE core. This construction gives you 190 pounds of tensile strength in a thinner diameter than the standard 3/16-inch polyester lines. The thinner profile means less friction when the line runs over branches, which is noticeable on trees with tight crotches.

In testing, the bright orange color was easy to track through dense canopy, even at 60-plus feet. The throw weight includes a 1-inch nickel-plated ring that attaches securely to the line. The whole package fits into the drawstring bag, which keeps everything contained in your truck or gear box.

The 4.3-star rating is the lowest in this roundup, and the reviews tell a clear story. Many users love the convenience and effectiveness, but a significant number report quality control issues. Some lines arrived frayed at the ends, and the storage bag is tight enough that coiling the line back in requires patience. The PE material is also stiffer than polyester, which makes coiling more difficult, especially in cold weather.

Who Should Buy This Kit

Arborists who want a complete, grab-and-go package with built-in storage. The included 600D bag is the main selling point here, and if you value organization on the job site, this kit makes sense. It is also a decent option for someone who wants to try polyethylene line without investing in a premium setup.

What to Watch Out For

Quality control seems inconsistent. Inspect the line and bag when you receive it, and do not hesitate to exchange if anything looks off. The 150-foot length is shorter than some alternatives, so measure your typical tree heights before committing. The stiff PE line requires more effort to coil neatly, especially in cold conditions.

7. GM CLIMBING Throw Line – Best High-Strength UHMWPE Line

The GM CLIMBING throw line is different from every other kit in this roundup because it is a standalone line, not a kit. But that is exactly why it belongs here. The 1.7mm UHMWPE (Ultra High Molecular Weight Polyethylene) line delivers an astonishing 650 pounds of tensile strength in a cord that weighs almost nothing. For climbers who already own a throw weight and want to upgrade their line, this is the one to get.

I first tried this line after a professional arborist recommended it on the r/arborists forum. The difference in slickness compared to polyester is immediately noticeable. This line slides over bark like it is lubricated, which means less effort on retrieval and fewer stuck lines in hairy trees. The 180-foot length covers virtually any tree you will encounter.

The 12-strand hollow braid construction serves two purposes. First, it creates a smooth surface that glides over branches with minimal friction. Second, it allows you to splice the line if you want custom loops or attachments. The UHMWPE fiber is resistant to water, UV, chemicals, and abrasion, which means this line will outlast polyester and polyethylene alternatives by a wide margin.

The catch is that you need to pair it with a quality throw weight. The 1.7mm diameter requires proper knot technique. I recommend a girth hitch or slippery hitch for attaching the throw weight. The thin diameter also means it can be harder to grip during retrieval, so gloves are essential. But for the strength-to-weight ratio, nothing else comes close.

Who Should Buy This Kit

Experienced arborists and serious tree climbers who already own a throw weight and want to upgrade to the best line available. The 650lb tensile strength makes this line capable of handling heavy climbing ropes and rigging setups. If you have struggled with polyester lines getting stuck in rough-bark trees, the UHMWPE material solves that problem.

What to Watch Out For

This is a line-only purchase. You will need to supply your own throw weight, which adds to the total cost. The ultra-thin 1.7mm diameter requires practice to handle confidently, and you must use proper knots to avoid slippage. Also, UHMWPE has low melting point, so avoid heat exposure near the line.

8. FORESTER Dyneema Throw Line Kit – Best Premium Dyneema Line

The FORESTER Dyneema kit is the newest and highest-rated product in this roundup with a perfect 4.8-star average. Dyneema is the brand name for UHMWPE fiber, and it is widely regarded as the gold standard for throw line material. The 2.2mm diameter is slightly thicker than the GM CLIMBING line, which makes it easier to grip and handle during retrieval.

What makes Dyneema special is the combination of incredible strength and near-zero friction. This line slides over bark, through crotches, and around branches with minimal resistance. I have seen arborists on forums consistently rate Dyneema lines as the best throw line material available, and this kit gives you 180 feet of it paired with a 15-ounce throw weight.

The 2.2mm diameter hits a sweet spot between the ultra-thin 1.7mm lines and the thicker 3/16-inch polyester options. It is thin enough to slide through tight crotches but thick enough to grip comfortably. The low-memory construction means it feeds out without kinking, and the abrasion-resistant design should hold up to daily professional use.

With only 16 reviews, this kit does not have the extensive track record of the standard FORESTER kit. However, every single review is positive, with users specifically praising the throw distance and the slickness of the line. One user reported excellent results using it with an air cannon, which tells you something about how well this line performs under pressure.

Who Should Buy This Kit

Professional arborists and serious climbers who want the best throw line material available and do not mind paying a premium for it. The Dyneema line outperforms polyester and polyethylene in every measurable way. If you climb daily and need a line that will not let you down, this is the upgrade to make.

What to Watch Out For

The limited review count means you are an early adopter. The price is higher than polyester kits, which is expected for Dyneema but may not fit every budget. Also, because the line is so slick, you need to be more careful with knot security on the throw weight attachment. A slippery hitch is your best friend here.

How to Choose the Right Throw Line Kit for Tree Climbing

Picking the right throw line kit comes down to four key factors: line material, throw weight, line length, and storage. Let me break each one down based on what I have learned from testing these kits and talking with professional arborists.

Line Material Matters More Than Anything Else

The material of your throw line determines how well it slides over branches, how long it lasts, and how much weight it can handle. There are three main options you will see in throw line kits.

Polyester is the most common and most affordable. It offers good slickness, decent durability, and low memory. Polyester lines like the ones in the FORESTER and MGP SUPPLY kits are great for beginners and general use. Expect a tensile strength around 190 to 200 pounds.

Polyethylene is lightweight and inexpensive but stiffer than polyester. It works but tends to kink more and has more friction over rough bark. The Weaver and FORESTER Professional kits use PE lines, and while they get the job done, most professionals prefer polyester or better.

UHMWPE and Dyneema are the premium options. These fibers deliver 650-pound tensile strength in ultra-thin diameters, near-zero friction, and exceptional durability. The GM CLIMBING and FORESTER Dyneema kits use these materials, and the performance difference is immediately noticeable. If your budget allows, go with Dyneema or UHMWPE.

Choosing the Right Throw Weight

Throw weight determines how far and how accurately you can place your line. Professional arborists consistently recommend 16 ounces as the minimum for reliable performance. Lighter weights like 9 or 11 ounces work for shorter throws but struggle to reach high canopy branches, especially in windy conditions.

If you are a beginner, I recommend starting with a 14 or 15 ounce weight. It provides enough mass for consistent throws without being so heavy that it wears you out. Kits like the XBEN and Aystkniet that include multiple weight options are great for finding your personal preference.

For tall trees over 70 feet, you will want a 16-ounce weight paired with a launcher like a BigShot for consistent results. Hand throwing at that height requires significant technique and practice.

Line Length and Diameter

Most throw line kits come in 150 to 180 foot lengths. For residential tree work, 150 feet covers most situations. For commercial arborist work involving tall hardwoods or pines, go with 166 to 180 feet. Running out of line halfway through a throw is frustrating and avoidable.

Diameter affects both grip and friction. Thinner lines like 1.7mm UHMWPE slide better but are harder to grip. Thicker lines like 3/16-inch polyester are easier to handle but create more friction. The 2.2mm Dyneema in the FORESTER premium kit hits the ideal balance for most climbers.

Storage and Organization

This is the factor most people overlook. A tangled throw line wastes time and tests patience. Kits that include a storage bag or cube, like the FORESTER Professional and XBEN kits, keep your line organized and ready to deploy. If your kit does not include storage, invest in a line cube or stuff sack separately.

The Matriosac throw line storage bag is popular among professionals because it has gear storage underneath the line compartment. But any dedicated container that lets you feed line out without tangles will work. The key is never to stuff loose line into a pocket or backpack.

Final Thoughts on the Best Throw Line Kits for Tree Climbers

After testing all eight kits, the FORESTER Arborist Throw Line Kit remains my top recommendation for most climbers. It offers the best combination of line quality, throw weight, length, and value, backed by over 3,300 verified reviews. For professionals who want the absolute best line material, the FORESTER Dyneema kit and the GM CLIMBING UHMWPE line deliver unmatched performance with near-zero friction and exceptional strength.

The best throw line kits for tree climbers in 2026 range from budget-friendly polyester options to premium Dyneema rigs. Whether you are a weekend warrior trimming branches or a professional arborist climbing daily, there is a kit in this lineup that fits your needs and budget. Pick the one that matches your typical tree heights and climbing frequency, invest in good throwing technique, and you will spend less time fighting tangles and more time doing productive work aloft.
