From the trails to the road, the Altra Men's Performance 1/2-Zip Shirt provides adaptive protection and convenient performance. The Zerolite fabric fends off light elements, while the mesh inserts provide on-the-go breathability and ventilation, so you don't have to think twice about temperature regulation or moisture management. Meanwhile, the on-seam thumbholes allow you to batten down the hatches, and reflective details enhance your overall visibility in low-light conditions. Though, better yet, the shirt packs down into its own chest pocket, so you're able to toss in your pack or into a pocket should the sun come out to play.

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
