In addition to its superior breathability, this wader also features a carefully considered seam design that enhances mobility on the trail, as well as prevents seam blowouts to ensure years of durability. Pass-through handwarmer pockets give your fingers a break on chilly mornings, and the chest storage pocket keeps your fly box, pliers, nippers, and other tools close at hand. As an added bonus, Simms added an internal zipper carrier that's meant to sync with Simms' Tippet Tender pocket (sold separately) for the ultimate in convenience.
