Echo Long-Sleeve T-Shirt - Women's

What Our Gearhead® Experts Are Saying:

"This is my go-to layer for running, hiking, or layering under a pack. It’s so light you forget it’s there, and the breathability is unreal. I can wear it from cool mornings to sunny afternoons without overheating—it’s a year-round workhorse in my kit."

We count on the Outdoor Research Echo Long-Sleeve T-Shirt for big-mile days and high-output movement when weight and breathability matter most. Built with trail-proven performance, this featherlight tee keeps us cool, dry, and protected when we’re moving fast under sun or cloud.

With a barely-there feel, this top excels as a base layer or standalone in warm conditions. The AirVent™ fabric wicks moisture and dries fast, while flat seams and Polygiene® odor control keep things comfortable on extended efforts. Whether we’re hiking peaks or logging trail runs, this is the layer we reach for when we want performance without the bulk.
