Size & Fit

Slim fit, intended to follow the contour of the body. Take your usual size for a close base-layer fit; size up if you want more room through the body or plan to layer underneath. Shoulder panels eliminate the top shoulder seam and the side seams are offset and wrap to the front, so nothing hard sits under a pack strap.
