The women’s Irico Short Sleeve Shirt is a light, technical, and breathable hiking top created for warm weather alpine pursuits and long summer days on the trail. It’s made of Columbia’s Omni-Freeze ZERO™ sweat-activated cooling polyester, which has Vent-Air meshing and Omni-Wick™ moisture management technology. The result is a slim-fitting front-buttoned shirt that keeps wearers airy and dry when out on rocky side-trails, or when undertaking some gardening work on a June afternoon.
