What Our Gearhead(R) Experts Are Saying: "I wear the Echo Tank-Plus on the hottest days-whether I'm hiking, running, or climbing. It's incredibly light, dries super fast, and gives me room to move without any cling. The drop-tail hem adds nice coverage when I'm wearing a pack, and it doesn't ride up."When we're chasing shade on exposed trails or pulling plastic at the gym, the Outdoor Research Echo Tank-Plus keeps us cool, dry, and moving freely. Designed with ultralight, breathable AirVent(TM) fabric and a movement-friendly fit, it's made for high-output days when comfort and airflow matter most. UPF protection guards against the sun, and the racerback design enhances freedom of movement whether we're reaching, stretching, or layering it under a shell. With ActiveFresh(TM) odor control and moisture-wicking performance, this tank stays fresh and comfortable through warm-weather sessions and multi-day adventures alike.
