Jacquard print and standup collar harken back to SPYDER?s roots, but GORE-TEX INFINIUM waterproof/breathable fabric and AquaGuard zippers bring this classic back to the future. Blending the moisture wicking and insulative properties of merino wool with the durability of nylon and the performance of GORE-TEX, this half zip excels as a standalone on the mountain or apr?s.
