Stash the ExOfficio Men's Fraser Crewneck Long-Sleeve Travel Shirt in your carry-on bag whether you're heading out on a weekend getaway to the mountains or to a multi-day hiking trek. You'll stay warm thanks to the S° Warm hollow fibers, which trap your body heat for quick-drying warmth that won't add bulk to your look. Odor-resistant Silvadur technology means you can wash this long-sleeve pullover less, wear it more, and get a little more room back in your bags. The lightweight stretch fabric will keep up with you and keep you comfortable. Forward-rolled shoulders enhance movement, making it easier to reach for the rails on the trail or your overhead suitcase on the plane.
