CAYL Men's Stripe B.L. Short Sleeve T-Shirt - Green SIZE:M The 15d fabric is featherlightThis is the Stripe BL Short Sleeve T Shirt from CAYL. The BL in the name stands for base layer, which should give you a bit of an idea what the score is here. It's super light, it's breathable and it's quick drying, with that dash of spandex in the recipe meaning it's nice and flexible whether you're climbing, running or cycling.
