While our Simms waders keep our lower half dry in the water, the G4 Pro Jacket keeps our upper half dry in the wet weather where the fish bite best. The shell features the most durable GORE-TEX waterproofing, GORE-TEX Pro, for guide-grade protection in the toughest conditions with an adjustable storm hood and watertight cuffs to prevent water from sloshing up our arms when we dunk our hands underwater or catch and release fish. Going above and beyond your average rain shell, it also features a flip out vertical loop fly patch, tons of on-body storage pockets, and spacious rear game pockets to keep fish or stash extra layers.
