Like a puffy made with fleece instead of feathers, the men's REI Co-op Flash Power Air jacket is sleek, light and easy to layer, keeping you warm on backcountry trails without feeling bulky.


  • By encapsulating its fleecy yarns between layers of fabric, Polartec® Power Air™ fleece warms more efficiently with less weight
  • Because the fleece is encapsulated, Power Air sheds up to 5x less microfiber into the environment than other premium mid-layer fabrics
  • Jacket stretches 4 ways, breathes, wicks away moisture and dries quickly
  • Cut for easy layering and easy moving, with spandex binding at the cuffs and hem
  • Zippered hand and chest pockets keep essentials secure
  • Seam-free shoulders reduce chafing under pack straps
  • Thumbhole cuffs add ease to layering
  • Made to reflect our love for people and the planet through the use of recycled polyester and bluesign®-approved materials
  • Recycled materials keep waste out of landfills and bluesign®-approved materials conserve resources and protect the health of the environment, workers and wearer (you!)

Sizing Notes

Measurements are stated in inches unless otherwise indicated.

SHORT: Some pants are available in short sizes, which generally means an inseam that is 2.5 inches shorter than regular sizes.

TALL: Some pants, shirts, jackets and parkas are available in tall sizes, which generally means an inseam that is 3 inches longer and a rise that is 1 inch longer, a shirt or jacket body that is 2 inches longer, a parka body that is 2.5 inches longer and sleeves that are 2.5 inches longer than regular sizes.

Capri or cropped pants have an intentionally shorter inseam—reference the technical specs instead of this chart.
