Hummingbird Hammocks tree straps are the pick: 1.55 oz for the pair with a published 400 lb combined capacity, and named best ultralight straps in 99Boulders' test. For adjustability at a still-light 4.3 oz, the ENO Helios is the alternative.
Part of our hammock gear hub, and the weight-first cut of the best hammock straps. 99Boulders defines ultralight straps as roughly 8 feet long and under 5 ounces — which in its test means the Hummingbird and the Helios, and nothing else.

The numbers, side by side
| Suspension | Weight | Capacity | Length | Adjustment |
|---|---|---|---|---|
| Hummingbird tree straps | 1.55 oz | 400 lb combined | 8 ft 4 in | Single attachment point |
| ENO Helios | 4.3 oz | 300 lb combined | 8 ft 1 in | Cord micro-adjust |
| DutchWare Spider Web 1.5 | 1.5 g per foot of webbing | 1000 lb breaking strength | Fixed lengths, 10 ft available | Depends on your hardware |
| Hammock Gear whoopie sling | Not published | Not published | Adjustable within range | Continuous |
| Kammok Python 10 (reference) | 8.2 oz | 500 lb combined | 10 ft 2.5 in | 20 fixed loops |
The Python is in the table as the benchmark, not as a pick: it is the strap most people should buy and it is five times the weight of the Hummingbird. That is the trade this page is about.
1. Best ultralight straps
Hummingbird Hammocks Tree Straps
1.55 oz for a 400 lb rating — the lightest credible straps in the category by a wide margin.
Specifications
- 400 lb combined capacity
- 8 ft 4 in long
- 1.55 oz
- Single attachment point
Source: 99Boulders 2026 hammock strap test. We publish specs we can attribute and leave the rest blank rather than assuming a typical value.
What it does well
- 1.55 oz against the Atlas's 9 oz is a real pack-weight difference
- 400 lb capacity despite the weight
Where it falls short
- One attachment point means the hang angle is set with a knot, not a loop
- 8 ft 4 in is the shortest here — big trunks will defeat it

2. Fine hang-angle adjustment
ENO Helios Hammock Suspension System
4.3 oz with a cord micro-adjust — dialing in the hang is faster and more precise than any daisy chain.
Specifications
- 300 lb combined capacity
- 8 ft 1 in long
- 4.3 oz
- Microtune cord adjustment rather than fixed loops
Source: 99Boulders 2026 hammock strap test. We publish specs we can attribute and leave the rest blank rather than assuming a typical value.
What it does well
- Micro-adjustment beats jumping between fixed daisy-chain loops
- 4.3 oz for the pair is genuinely light
Where it falls short
- 300 lb is the lowest rating of the straps here
- Shortest length in this group

3. The lightest webbing you can buy
DutchWare Spider Web 1.5 Tree Straps
1.5 grams per foot of UHMWPE webbing with a 1000 lb breaking strength — the lightest tree-protecting strap material on the market.
Specifications
- 1 in wide UHMWPE webbing
- 1000 lb breaking strength
- 1.5 g per foot
- DutchWare also lists a 2 in version at 1500 lb and 3.2 g per foot
- Sold in fixed lengths including a 10 ft option
Source: dutchwaregear.com Spider Web 1.5 product listings, 2026. We publish specs we can attribute and leave the rest blank rather than assuming a typical value.
What it does well
- At 1.5 g/ft a 10 ft pair is well under an ounce of webbing
- One inch wide, so it still meets tree-protection width rules
- Almost no stretch, and it does not soak up water
Where it falls short
- Breaking strength is not a working load — derate it hard
- Slippery webbing needs the right hardware; this is not a beginner's daisy chain

4. Adjustable suspension without webbing
Hammock Gear Whoopie Sling
An adjustable Amsteel sling that replaces bulky daisy-chain webbing at the hammock end of the suspension.
Specifications
- Adjustable Amsteel whoopie sling, sold singly
Source: hammockgear.com product page, 2026. We publish specs we can attribute and leave the rest blank rather than assuming a typical value.
What it does well
- Far less bulk and weight than daisy-chain webbing
- Infinite adjustment within its range
Where it falls short
- Still needs a tree-protection strap — a whoopie sling alone is not tree-friendly
- Published working load is not stated on the listing

5. Best straps overall
Kammok Python 10 Hammock Straps
Longer, lighter and higher-rated than the category default — the straps most people should buy.
Specifications
- 500 lb combined capacity
- 10 ft 2.5 in long
- 8.2 oz
- 20 attachment points
Source: 99Boulders 2026 hammock strap test. We publish specs we can attribute and leave the rest blank rather than assuming a typical value.
What it does well
- 500 lb combined is the highest rating in 99Boulders' 2026 strap test
- 10 ft reaches around trees the 9 ft straps cannot
- 20 attachment points give finer hang-angle control
Where it falls short
- Slightly bulkier packed than a minimalist strap
- Daisy-chain webbing is still coarser adjustment than a cord system
Illustrative photograph of the category, not this exact product.
What you give up to save the ounces
- Length. Ultralight straps are 8 ft 1 in and 8 ft 4 in here. A mature trunk eats a surprising amount of that before anything reaches the hammock, and a 10 ft strap simply reaches where an 8 ft one does not.
- Attachment points. The Hummingbird has one. You set the hang angle with a knot or a hitch rather than by picking a loop, which is a learned skill rather than an obvious one.
- Capacity. The Helios publishes 300 lb combined — the lowest figure in 99Boulders' test. If your loaded weight is anywhere near that, this is not the strap to buy.
- Forgiveness. Thin webbing and slippery UHMWPE want the right hardware and the right knots. Daisy-chain webbing tolerates being got wrong.
Breaking strength is not a working load
DutchWare publishes 1000 lb breaking strength for the 1-inch Spider Web 1.5 and 1500 lb for the 2-inch version. Those are the numbers at which the webbing fails, not the numbers at which it is safe to load it. Everything else on this page publishes a combined capacity instead, which is the figure to compare. Do not put a breaking strength next to a capacity and conclude the webbing is stronger.
The same reasoning runs through hammock weight limits: your setup is rated at the capacity of its weakest published component, and an unrated component is not a strong one.
One inch wide, whatever the weight
Cutting weight does not mean cutting width. The Spider Web 1.5 is 1 inch wide at 1.5 grams per foot, which is the point of it: you keep the tree-protection width that many parks now require while carrying almost nothing. Thin cord against bark is the thing to avoid, not thin webbing — the reasoning is in are hammocks bad for trees?
Whoopie slings, and where they fit
A whoopie sling is not a tree strap. It is an adjustable Amsteel link between the strap and the hammock, and it replaces bulky webbing on the hammock side of the suspension. Paired with a short tree hugger it is one of the lightest complete systems available — but the hugger is not optional, because a sling alone against bark is the thing we just told you not to do.
What we would buy
- Lightest credible option: Hummingbird tree straps, 1.55 oz for 400 lb.
- Light with easy adjustment: ENO Helios, provided 300 lb clears your loaded weight.
- Building your own suspension: DutchWare Spider Web 1.5, derating the breaking strength properly.
- Lightest complete system: a whoopie sling plus a short tree hugger.
- Most people, most of the time: the Kammok Python 10 — heavier, longer, and the one we would still recommend first.
Common questions
What counts as ultralight hammock straps?
99Boulders uses roughly 8 feet of length and under 5 ounces for the pair. In its test only the Hummingbird tree straps at 1.55 oz and the ENO Helios at 4.3 oz qualify, against 8.2 oz for a Kammok Python 10 and 12 oz for Grand Trunk straps.
How much weight can ultralight hammock straps hold?
The Hummingbird straps publish 400 lb combined at 1.55 oz and the ENO Helios 300 lb at 4.3 oz. Light does not mean weak here, but the Helios figure is the lowest in the category, so check it against your loaded weight.
Are ultralight straps long enough for big trees?
Often not. At 8 ft 1 in and 8 ft 4 in they are the shortest straps in the test we cite, and a mature trunk uses much of that in the wrap. If you camp in old forest, the weight saving may cost you sites.
Are thin straps bad for trees?
Width is what protects bark, not thickness or weight. The DutchWare Spider Web 1.5 is 1 inch wide at 1.5 grams per foot, which keeps you inside the minimum-width rules many parks now apply. Bare cord or rope against bark is the thing to avoid.
Do I need a whoopie sling as well as straps?
No — it is an alternative to webbing on the hammock side, not an addition. Used with a short tree hugger it is one of the lightest systems going; used alone against a trunk it damages the tree.
