The Outdoor Research Men's Echo Long Sleeve Tee is the ultimate choice for anyone seeking an ultralight, breathable, and technically advanced garment for outdoor activities across all four seasons. Whether you are heading out for a trail run, summer hike, spring ski tour, or need a functional base layer for colder days, this shirt with a featherweight of just 130 g ensures total freedom of movement. It is crafted from eco-friendly 100% recycled polyester with bluesign® certification, offering exceptional next-to-skin softness.

The ultralight fabric with a density of 78 g/m² features advanced AirVent™ technology, providing superior air circulation and lightning-fast moisture wicking. The material is remarkably quick-drying and stretchy, performing brilliantly even during the most intense athletic efforts. For worry-free movement under bright sun, it provides UPF 15 sun protection, while the proven ActiveFresh™ odor control treatment actively neutralizes bacteria and prevents unpleasant odors during multi-day use.

Designed in an athletic, body-hugging cut (Trim Fit), the shirt sits smoothly against the body, allowing effortless wear under a backpack or other clothing layers. Carefully placed flatlock seams prevent chafing for maximum comfort, while a minimalist reflective logo ensures added visibility at dusk or in early morning hours.
