Light synthetic baselayer keeps you dry and cool and has 15-UPF sun protection; updated with a lighter, more breathable fabric that wicks and dries faster.

This top provides precious sun protection and a cool, drying airflow. Made with our lightest-weight Capilene® performance baselayer fabric (3.4-oz 100% recycled polyester with 15-UPF sun protection and Gladiodor® odor control for the garment), this top wicks moisture, breathes, and dries in a flash. Long enough to tuck in, it has a rib-knit collar that's soft and pliable against the skin, and features raglan-style sleeves that allow a full range of motion and pack-wearing comfort. Recyclable through the Common Threads Recycling Program.
