Stay cool and protected from the sun when you are outdoors this summer with the Macpac Women's Brr Tee. Designed for adventures under the sun, they're made from a fabric that's cooling, wicking, and quick-drying. Triple Chill Effect fabrics combine cooling minerals with active wicking and rapid drying technology to reduce the temperature of your skin. This active T-shirt has flatlock seams for next-to-skin comfort under backpacks and running vests and an underarm gusset for plenty of mobility. A Polygiene treatment uses recycled silver to help prevent the growth of odour-producing bacteria. Perfect for summer hikes and days spent outside.
