Outdoor Research lightweight Echo S/S Tee is perfect for high-exertion activities and warm weather. Available in multiple colors, the soft, comfortable AirVent™ fabric breathes, wicks moisture and dries quickly when you pause to take in the view. Raglan sleeves and flat-seam construction reduce chafing, Polygiene® prevents odor, and UPF 15 protection helps prevent sunburn on clear, warm days.
