When you need the ultimate in hot weather performance, reach for the Sol Cool Crew. This highly functional fabric protects from the elements wherever your adventures take you. Sol Cool features Icefil technology, which binds Xylitol, a compound found in the birch tree and mint gum, to fabric fibers. It cools the body up to five degrees upon contact with moisture. A UPF 50+ rating, the highest for a garment, guards against UVA and UVB rays even when wet, and the Intelligent Moisture Control fabric wicks efficiently to keep you dry. Underarm gussets provide maximum mobility, and the active stretch fabric is odor resistant.
