Wearing the Castelli Wool Long Sleeve Zip Neck Base Layer is probably the coziest thing next to carrying a cute baby sheep on your shoulders. It is constructed of ultra-fine merino wool that feels extraordinarily soft next to your skin, and that wicks moisture and retains warmth even when wet. Wool also has natural antibacterial properties that keep you smelling fresh. This base layer features a tall, zip-up collar and flat-lock stitching.
