Ranking as our most durable waterproof rain jacket, this uninsulated hard shell is built with the functionality, features, and materials hardcore waterfowl hunters demand. When packable rain gear won’t cut it, its heavy-duty, 4-layer laminated waterproof fabric provides rigid protection from punctures, abrasion, and snags.

The jacket is crafted with a purpose-driven fit and gusseted underarm for no lift, full articulation, and unrestricted shooting ability. While retaining a comfortable ergonomic fit, it’s designed with minimal seams for reduced weight and added durability.

The jacket’s bonded lining was carefully chosen for frictionless, non-chaffing movement against underlying clothing, while remaining durable for extensive hard use. Engineered with a focus on maximum long-term reliability, we optimized seam construction, taping, and seam junction reinforcements for added longevity.

Features include Sherpa fleece lined hand pockets, front cargo pockets for shells and storage, waterproof cuffs, a two-way adjustable storm hood for complete protection and visibility, and pit zips for temperature regulation. The jacket’s overall length is balanced for both field use and while wearing waders in flooded timber situations. The hem cinch with cord keeper may also be adjusted to effectively shorten the jacket length for wading in deeper water.
