The Gust transfers the load efficiently from an anatomically contoured foam back panel to webbing hip belts. The pack is top loading, has a top retention strap, and has an entire body made of Spectra Gridstop nylon. The packs are generously sized so that you can fit all of your gear inside the pack, even on lite winter trips. When your load is less bulky, you can trim the capacity by cinching the straps down. The lightest hip-belted pack made by GoLite for multi-day hiking, ski and winter trips, or vertical climbing. Comes in three sizes (s,m,l) and three colors (night, fire, forest). Carries 30 pounds comfortably. Includes large extension collar, front & rear equalized haul loops, 2 tool holders, and 1 rear pocket.
