Your favorite cotton tee is dialed for kicking back at camp or puttering around in the garage, but it can't hold a candle to the moisture wicking and breathability of Alpinestar's Trailstar Men's Short Sleeve Jersey. It feels like cotton, but is actually made of quick-drying polyester and comes complete with breathable mesh side panels to help you stay cool when the trail turns uphill and the going gets tough. Alpinestars also includes a wide, low collar for increased cooling and comfort and an elongated and lowered back hem so there are no peek-a-boo gaps when you're bent over the bars.
