Don't even think about that treadmill! The REI Airflyte crew shirt brings an extra layer of warmth to outdoor workouts in cool weather.

Fabric provides UPF 50+ sun protection, shielding skin from harmful ultraviolet rays. Thumb holes keep sleeves in place while your arms are in motion. Ergonomic seam placement complements your natural movements, and flat seams reduce chafing. Droptail hem increases coverage and protects from splashes; and raglan sleeves enhance freedom of motion. The active fit of the REI Airflyte crew shirt moves with you during exercise.
