Total sun protection shouldn't mean roasting like a succulent wild boar on a spit. The Sol Cool™ Ultimate Hoody's design blocks the rays while the Sol Cool™ fabric reduces your skin temperature where it comes in contact with sweat. Mesh under the arms and on the sides lets breeze in, and the thumb slots and scuba-style hood fulfill the need for thorough coverage. Two vents on the back of the hood chill your neck, and one side seam zip security pocket keeps your phone or other valuables handy. A soft Sol Cool™ fabric lining keeps you and the front zipper on good terms, so don't worry about ruining your chest hair coiffure. Our Sol Cool™ Icefil® knit fabric is embedded with xylitol, derived from white birch trees. When in contact with sweat, xylitol can decrease skin temperature by 5°F, and the Icefil® fabric wicks the moisture to the garment's surface. The same Icefil® treatment blocks UV rays for a UPF 50 rating, giving you more time to enjoy the sun.
