Arc'teryx Ether Crew - Long-Sleeve - Men's - $52.47

Arc'teryx made the Men's Long-Sleeve Ether Crew just the right weight for a brisk hike, run, or backpacking stint in cool high-altitude air. Silky-textured synthetic fabric draws perspiration away and lets it evaporate before you ever feel a chill, and flatlocked seams won't chafe under your backpack straps or hipbelt. Gusseted underarms mean the shirt won't ride up as you raise your arms to climb, scramble, or air-guitar to the '80s hair mix on your portable MP3 stereo. - $52.47
