Originally developed as a waterproof insulation layer for sailors, this Men’s Crew Hooded Midlayer Sailing Jacket 2.0 is an excellent insulated jacket that can also be worn as an outer layer. It is built with Helly Tech® Protection, a waterproof, windproof, and breathable midlayer sailing jacket. It features an updated lining constructed with Polartec® fleece and a polyester insulation lined with taffeta in the sleeves for easy on and off. The articulated elbow and shoulder allow for greater freedom of movement. The center front Ykk® Vislon® zipper is stronger and more saltwater resistant, withstanding corrosion. Its design also includes a hood that can pack down into the collar. Both the collar and the hand pockets have a brushed Tricot lining. Shell: 100% Polyester. Lining: 100% Polyester (Recycled). Lining 2: 100% Polyester.
