The new front-runner in your batch of sleeveless summer tops. With generous cooling mesh around the arm holes and the T-back, the Sol Cool™ Tank keeps the breeze moving. Curved front and back hems reveal additional mesh at the hips so you can wander and cavort in comfort and style. 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.
