Gregory: Iso Backpack

While Gregory designed their Iso pack for adventure racing, we've seen it on the backs of a few day hikers and athletic tourists. That's because the Iso features a lightweight and stretchy G 30 fabric that remains resilient to the rigors of constant motion. While the G 30 fabric is more than 75% lighter than the materials found in other Gregory packs, it's also coated with a silicone treatment that makes the fibers stretch instead of shredding. Like the smaller Reactor racing pack, the Iso can accommodate a 120-oz. hydration reservoir (not included), but it also features more room for food or clothing and an expandable front pocket that easily accommodates a cycling or climbing helmet. We found that the mesh waist belt pockets were just the right size for energy gel packets--a small feature you usually don't find on other adventure racing backpacks.
