"The Patagonia Capilene Daily T-Shirt is built for high-output days in the heat. The wicking finish and HeiQ Mint odor control work together so the shirt stays comfortable and fresh across back-to-back days, which is what makes it worth packing on a longer trip where laundry isn't an option. What Our Gearhead® Experts Are Saying:""I wear this on every sweaty approach because the wicking finish pulls moisture off my skin fast enough that I'm not soaked through by the time I hit the trailhead."""
