This fabric has been tested to block at least 98% of the sun's UVA and UVB rays. Nice wicking finish to help move moisture off the skin.

84% polyester / 16% Spandex for lots of stretch. Great for active sports and tight-fitting compression tops for athletic, military and workwear apparel. The tight fit and great stretch of tour 2307 poly/Spandex blend fabric allow for a comfortable wear and good lateral movement.
