What Our Gearhead(R) Experts Are Saying: "I wear the Echo short-sleeve for just about everything-trail runs, travel, fast hikes. It's insanely light, dries super fast, and doesn't cling when I sweat. Even better, it doesn't stink after a few days on the trail. This one always earns a spot in my pack."On days when we're chasing miles under the sun or knocking out back-to-back adventures, the Outdoor Research Echo Short-Sleeve T-Shirt delivers the breathability, weight savings, and next-to-skin comfort we rely on. It's the kind of ultralight tech tee that disappears while we're wearing it, but performs at every step. Made with moisture-wicking AirVent(TM) fabric and built-in Polygiene(R) odor control, the Echo keeps us dry, fresh, and moving. Flat seams prevent chafing, and the streamlined fit layers easily under other pieces or wears solo in the heat. Whether we're heading out for an hour or a week, this tee is a minimalist's dream layer.
