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 fibres 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.
