Sweetwater UL 43L Backpack

What Our Gearhead® Experts Are Saying:

"The Sweetwater is perfect for fastpacking or overnight trips. It fits like a dream thanks to its running-vest-inspired harness and load lifters. The recycled nylon is tough enough for rugged trails, and the included rain cover is a huge plus for unpredictable weather."

Set the pace with the Sweetwater UL 43L, an ultralight backpack that prioritizes fit, comfort, and durability. Designed with a running-vest-style harness, this pack hugs the chest, back, and shoulders for a secure carry, even on dynamic trails. Its proprietary Load Wrangler Plus system transfers weight from shoulders to hips, while adjustable straps and an anatomical back panel ensure stability and comfort. Built with ultralight recycled regen nylon made from discarded fishing nets, the Sweetwater UL 43L offers eco-conscious performance without compromise. A spacious main compartment with an expanding spindrift collar accommodates overnight essentials, while oversized stretch-mesh pockets provide quick storage for on-the-go access. An integrated rain cover from recycled materials offers extra weatherproofing for those unexpected trail showers.
