The 7mesh Roam Long Sleeve Shirt uses an open fabric structure and a textured backer to keep air moving instead of trapping heat against skin, whether the day is spent on a bike, a trail, or a run. The articulated fit leaves room in the sleeves for elbow pads, so the shirt works as well under a pack strap as it does under protective gear on a rougher ride. What Our Gearhead(R) Experts Are Saying:"I've climbed in this on warm afternoons and never had to peel it off. The backer keeps the fabric moving away from my skin instead of sticking on the sweaty parts, which is the difference between overheating and just working hard."
