Thirteen colors is a lot of decisions for one tee, so start with what it does. The TASC® Long Sleeve Tee comes from the TASC® Performance line and is created using sustainable materials, including bamboo and organic cotton. TASC® Performance offers an SPF50, along with natural odor control and moisture-wicking qualities, in a fabric that is amazingly comfortable. That makes it the long sleeve for a day in the sun on 30A, whether that means a paddle, a bike ride or a long lunch outside. Sizes run Small through 2X Large. Now the colors: Coast, Geyser, Aurora, Chambray, Spruce and Sea Green are a few of them.
