REI Co-op Expedition Cap
We're honoring the 50th anniversary of an REI-sponsored expedition on K2 with a throwback cap inspired by our own gear archives. Light insulation and snap-up earflaps offer cozy warmth on cold days.
- This hat takes design inspiration from the REI K2 Expedition Cap worn by climbers in the 1970s (though this modern take is made for casual wear, not technical mountaineering)
- 100% recycled nylon shell fabric with lightweight insulation
- Earflaps can be worn down or secured up with snaps
- Elasticized back for a snug fit
- Soft, stitched brim
- REI Co-op brand is certified to The Climate Label; we actively fund efforts to reduce carbon emissions across our business and support climate projects around the world
