The Bosun is one of our most versatile pieces. It is constructed using 345 gsm Merino wool with added nylon for strength and durability, 4-way stretch nylon patch-panels, removable hood, and zippered hand pockets. The Bosun works perfectly as a solo piece, over a base layer, or under one of our waterproof shells. Additional features include extreme 4-way stretch with reinforced elbow and shoulder patches, removable hood with hidden zipper tab, a rear touring style pocket and media ports throughout. Item is used but in great condition.
