Outdoor Research Echo Short-Sleeve T-Shirt - Plus - Women's Olympic, 4X

What Our Gearhead(R) Experts Are Saying: "I wear the Echo T-Shirt year-round-trail runs in the summer, as a base layer in winter, and even under my climbing harness. It's super breathable, dries in a flash, and never feels clingy. Plus, the odor control is a game-changer for multi-day trips." From high-output trail runs to alpine layering and everyday wear, the Outdoor Research Echo Short-Sleeve T-Shirt is our lightweight go-to for breathable, next-to-skin comfort. Made from 100% recycled polyester, this bluesign(R)-approved fabric is ultralight, fast-drying, and built for active performance in all four seasons. With built-in AirVent(TM) technology, the Echo wicks moisture and promotes airflow on hot climbs or humid trail days. ActiveFresh(TM) odor control keeps things fresh, even when we're logging multiple days on the move, while UPF 15 sun protection guards against UV rays during exposed pursuits. Flat-seam construction and a soft feel make it a layering-friendly essential, whether we're wearing it solo or building our kit from the base up.
