The crew at Hyperlite Mountain Gear are dedicated to making stripped-down, minimalist, high-performance outdoor for “goal-oriented adventurers.” That’s precisely what you can expect from the 2400 Southwest Pack, made to be used hard. The functional backpack is constructed from 100% waterproof Dyneema® Composite Fabrics, featuring a roll-top closure system with side compression straps for vertical compression. Additional details include three external solid Dyneema Hardline pockets, 1/4” foam back panel pad and proprietary seam sealing on all side seams and behind all sewn-on pack features.
