Reflective Whoopie Slings

    • Reflective tracers shine light back at night
    • Very low stretch, ultralight yet super strong Catzye™ Reflective Line
    • Performs like AmSteel®-Blue
    • Secure 10 in. (25.4 cm) bury


    A whoopie sling is a lightweight adjustable suspension line for a hammock. It has an adjustable loop with a bury where the line passes through itself that works much like the Chinese finger trap. When there’s no tension on the suspension, the loop adjusts freely. Apply weight to the hammock and the bury locks the loop.

    Reflective Whoopie Slings are made from Catzye™ which uses Trevo™ Ultra-High Molecular Weight Polyethylene (UHMWPE) fiber. The same type of fiber used for Dyneema® or Spectra®. Trevo is super strong and has very low stretch, making it perfect for whoopie slings.

    So what makes this different from AmSteel-Blue? ..... reflective tracers. Shine light on the whoopie and the tracers reflect it right back. Your buddy should never run into your hammock suspension again. Or was that you? The tighter 12-strand construction makes it more snag-resistant than 8 strand AmSteel-Blue. A slick polyurethane coating helps the line slide easily through a relaxed bury.

    We start with 12 ft (3.7 m) of Catsye to build a 6 ft (1.8 m) whoopie sling that adjusts over a range of 2-6 ft (0.6-1.8 m). One end has a 3 in. (7.6 cm) spliced, fixed eye loop with a 12 in. (30.5 cm) lead that attaches to your hammock with a larks head knot. The other end attaches to the tree straps and has an adjustable loop with a secure 10 in. (25.4 cm) bury for superior holding power. A plastic bead is included on the adjustable loop and the tail is backspliced so neither can accidentally be pulled through the bury.

    Reflective Whoopie Slings are sold individually. Two are required for a hammock suspension. Choose two different colors, if you like, to more easily identify the head or foot end of your hammock.

    Trevo is manufactured by DSM Dyneema. Both Trevo and Dyneema are UHMWPE fibers with very similar properties. When braided into line, Catzye (Trevo) performs like AmSteel-Blue (Dyneema) for hammock applications.

    • DO NOT use in situations where personal safety or valuable property could be endangered.
    • DO NOT hang a hammock above any objects that could cause injury if you fell on them. DO NOT hang a hammock higher than you can fall without injury while in the hammock.
    • Inspect all hammock components before each use. DO NOT use if signs of damage are apparent to the rope, splice, webbing, fabric, stitching, or hardware. When exposed to direct sunlight and outdoor elements, deterioration can occur.
    • DO NOT exceed the working load. When used under dynamic (stress, jerk) conditions, additional care must be exercised. These conditions can reduce the working load by as much as 33%.
    • DO NOT stand in line with rope under tension; it may recoil (snap back) unpredictably if released or broken.
    • Misuse can result in serious injury or death.

    In no event shall Litesmith, LLC be liable for any direct, indirect, punitive, incidental, or special consequential damages, to property or life, whatsoever arising out of or connected with the use or misuse of its products.

      Whoopie slings are already a fantastic suspension option for hammock campers looking to cut down on their kit's bulk and weight, but these reflective whoopie slings from Litesmith take it even further. The reflective tracers woven into them are a great way to clearly mark your suspension in low-light, making these perfect for catching people's attention before running into your setup... or catching your own attention when you have to get up in the middle of the night!
