Amazingly warm for its weight, the men's REI Co-op Flash insulated jacket uses ShadowBaffle™ construction that's warmer than standard quilting. Plus it's made with 70% recycled insulation.


  • Lightweight, windproof, bluesign®-approved, recycled ripstop nylon shell and lining fabric has a DWR (durable water repellent) finish to protect against light rain and stains
  • 60 g Primaloft Silver Eco synthetic insulation is 70% postconsumer recycled content, bluesign® approved and highly breathable, compressible and warm even when wet
  • REI-exclusive ShadowBaffle construction is lab-measured to be at least 14% warmer than stitching through all layers like a standard quilt-through and is also more durable
  • Highly compressible jacket packs down small into its left hand pocket
  • Pack-friendly zippered hand pockets fit with a pack's hipbelt
  • Additional zippered chest pocket and internal drop-in pocket give you storage options for trail essentials
  • Zipper placket and cuffs are constructed to be easily repairable to ensure a long life for this jacket
  • Drawcord at hem and stretch binding at hood and cuff help conform to your body and keep out cold drafts

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.
