The Coalatree Switchback Short-Sleeve Shirt is built from Ice. Cafe fabric that repurposes the equivalent of three cups of grounds and ten plastic bottles per shirt. The fabric blocks UV rays, dries quickly, and resists wrinkles, and hidden zip pockets at the hip keep a passport or phone secure without ruining the clean, button-up look. What Our Gearhead® Experts Are Saying:"I wore mine three days straight through a humid trip before it started to smell like anything at all, and it dried out overnight hanging in a hostel room with no fan."
