This HydroSkin shirt is warm by itself on moderately cool days, and makes an ideal mid-weight addition between a thermal inner layer and a windproof outer shell. The perfect addition to your gear bag.

# 0.5-mm Terraprene™ keeps you insulated and stretches easily.

# ThermalPlush™ inner lining increases insulation, repels moisture and dries quickly.

# 4-way stretch PowerSpan™ outer layer allows easy, unrestricted mobility.

# Lycra underarms eliminate binding, adding to this top's superior function either as a single outer layer or as a base layer.

# Titanium laminate adhesive aids in body heat retention.

# DWR coating forces water to "bead" and roll off the material.
