Patagonia Biostretch 3 T-Shirt - Mens

Patagoinia Men's Biostretch 3 T-Shirt:  Featuring strategically placed open-mesh knit patterns that help release heat and invite airflow, this formfitting, high-performance baselayer provides optimum comfort during fast-forward endeavors in cold weather. Biostretch 3 fabric is silky-smooth next to the skin and glides easily beneath layers. Tube construction eliminates side seams and the chafing that goes with them. The soft crew-neck and Y-Joint™ sleeves reduce friction and increase mobility. Tuckable length. Made from 5.5-oz 95% polyester (73% recycled) and 5% spandex, with 50+ UPF sun protection. Recyclable through the Common Threads Recycling Program.
