The Trophyline Nimbus Back Band (BB-Nimbus-25) provides comfortable, adjustable support for long days in a saddle hunting setup. Slip the padded band around your upper or lower back and under your arms, then clip the nylon strap into your bridge carabiner. The 29″ x 4.75″ padded area is made from a 95% nylon / 5% spandex breathable, silent, and water-repelling 2-way stretch fabric that moves with you without digging in. Improved side adjustment buckles allow quick length modifications, letting you pull it snug for firm support or loosen it for a more relaxed, reclined position. The band rolls up easily for convenient storage and transport, making it an essential accessory for added comfort and support in the tree.
