This lightweight jacket from our Tech Pack collection has a clean, simple appearance that's paired with an innovative design. The sturdy cotton fabric actually contains a waterproof membrane sandwiched between 2 layers of cool cotton that helps you stay dry without looking or feeling like a rain jacket. Dry and durable:The innovative fabrication combines 3 layers—cotton on the outside for a soft, sturdy hand feel, a waterproof membrane in the middle to help keep you dry and cotton against your skin for cool, familiar comfort. Pop your collar:A sealable stand collar helps seal out moisture and cool air to help keep you warm in bad weather. The collar tab features a unique, snag-free closure system that replaces the classic hook-and-loop design. More benefits:The side pockets and flap-over front pockets let you securely store your essentials. Nike Sportswear Tech Pack Men's Storm-FIT Cotton Jacket - Brown - 50% Organic Cotton.
