Size E bonded nylon thread is the industry standard for parachutes. It's a very robust thread that has been specifically matched to the parachute fabric and webbing we use on our hammocks and tree straps./p>

All of our gear is also sewn using ball-point needles. These needles gently guide webbing fibers out of the way of the thread rather than tearing or piercing, keeping as much of the material's original strength as is possible./p>

Our whoopie sling system uses the same mechanical concept as a Chinese Finger Trap to provide a system that is easy and quick to adjust during setup, but instantly locks up when weight is applied.

Adjustment is as easy as pulling a string. To lengthen the tree strap, simply pull on the loop. To shorten the tree strap, simply pull on the knotted string.

Thin straps or ropes can damage tree bark by applying too much pressure on a small area of the tree. Our Ultralight Tree Straps keep the load spread across a larger surface area, protecting all those wonderful trees we need to keep on hanging!

Using thin and light, yet incredibly strong 1-inch Dyneema webbing allows us to produce a very small packing and lightweight strap while maintaining the industry-accepted safe tree strap width of 1 inch.

The lightest straps around, but also the smallest packing.

Both straps together barely measure up to a typical candy bar and at 1.55 ounces, weigh even less.
