Keep your cool.

Ex Officio designed its Men's Sol Cool T-Shirt to keep you cool in any hot-weather activity under the sun. A combination of polyester and spandex gives you the comfortable stretch you need whether you're backpacking, hiking, climbing, cycling, mountain biking, or running. Ice-Fil technology (containing xylitol derived from birch trees) wicks moisture and keeps you at a solid  five degrees cooler than the air around you. Ice-Fil technology also gives this shirt antimicrobial properties, meaning it won't stink as badly as you do after a difficult hike under the sun. Its natural fit includes raglan sleeves and an underarm gusset to give you the mobility you need to climb comfortably. Flatlock seams add comfort when you're backpacking with a heavy load on your shoulders.

Sol Cool Short-Sleeve Tee

Sol Cool Short-Sleeve Tee

The Sol Cool Tee lives up to its name with Icefil® treated fabric. Xylitol, a compound also found in the birch tree and mint gum, is woven into fibers and cools skin up to five degrees upon contact with moisture, which is efficiently wicked away to the fabric surface. The Sol Cool crew tee also has the highest sun protection rating for a garment, UPF 50+, so you can play all day out in the sun.
