Make everyday that much better with the Icebreaker Men's Everyday Short-Sleeve Crew Top. Made entirely from merino wool, this lightweight shirt is breathable, moisture-wicking, and naturally antimicrobial, meaning you can wear it multiple days in a row without any odors. The slim fit allows it to be easily layered under a midlayer during a cool weather hike, but it still looks great on its own once things warm up.
