We combined a full-featured shell jacket with our Eqwader liner jacket to create the most versatile systems jacket available. The shell is outfitted with Drake's Instinctive Features to be more effective during the hunt. The Eqwader liner jacket is fleece-lined to deliver warmth without weight or bulk - and to deliver unmatched versatility, the sleeves zip off to convert the liner to a vest. The vest option provides two more ways to layer versus a conventional 3-in-1, hence the name 3-in-1 Plus 2. Instinctive Features: Magnetic Chest Call Pouch on Shell and Liner, License/Key Pouch on Shell and Liner, Call Separator, Deep Water Handwarmer Pockets, Spring-Open(tm) Shell Pouches. Construction: 100% Waterproof/Windproof/Breathable Refuge HS(tm) fabric with HyperShield Technology(tm), Double-layer adjustable neoprene cuffs on shell jacket, Single-layer neoprene cuffs on liner jacket, Taped Seams Liner Materials: Eqwader Full Zip Jacket with Removable Sleeves.
