There’s a lot to love about Arista Brio-Tek shirts. Proprietary Brio-Tek fabric is lightly brushed to feel luxuriously soft and reduce chafing. Brio-Tek 150 contains a whopping 23% spandex so you can enjoy total freedom of upper body movement while riding. Add that it’s SPF 50, pil resistant, static free, wicking, and breathable to the list of features Brio-Tek offers. And if you do sweat – it’s no sweat. All Arista Brio-Tek shirts are treated with an environmentally friendly finish that ensures they stay fresh, hygienic and odor resistant. Brio-Tek 150 is ultra light-weight yet is not sheer or clingy.
