What Our Gearhead(R) Experts Are Saying:"I wore this on a hot trail run where most shirts would have me peeling it off by mile three. The merino wool breathed the whole way and never picked up any odor, even hours after I got back."A trail run through rising heat and shifting terrain asks a lot of a simple tee, and the Forest Footsteps T-Shirt from Icebreaker keeps up without complaint. Lightweight merino wool regulates temperature as effort builds, staying cool through the hard climbs and warm enough once the pace slows on the way down. Offset shoulder seams cut down on friction under a pack strap or hydration vest, letting the miles pile up without any distraction. It's a tee built to move at the same pace you do, mile after mile.
