Details

  • Polartec Power Dry utilizes 2 different yarns on either side of the fabric to enhance comfort: interior yarn wicks moisture, and exterior yarn dries quickly
  • The combination of the 2 yarns helps keep you dry during highly aerobic activities because it moves moisture away from skin faster than single-component fabrics such as cotton
  • Updated fabric protects skin against harmful ultraviolet light with a UPF rating of 20
  • Flatseam construction is soft and non-chafing next to skin; seams are designed to work under pack straps at shoulders
  • Underarm and side gussets promote freedom of motion
  • Dropped back hem stays tucked in
  • The REI Lightweight Polartec Power Dry long-sleeve crew features a next-to-skin fit that hugs the body and boosts fabric performance
