A single layer can have a bigger impact than you think. Our go-to, packable hoody houses the highest warmth-to-weight ratio of any fabric in our line, along with high breathability and a moisture-wicking stretch neck section for keeping your head on a swivel. This unique active mesh construction consists of hollow, tube-like fibers that absorb sweat quickly and efficiently—supporting insulation and heat-shielding properties to keep you temperature-regulated from the trail to the lift, and everywhere in between.

Details

The sun doesn’t take a break from the outdoors just because the temperature takes a dip, and neither should you. Harmful UV rays are amplified by rock, water, or snow on the trail, which makes covering up in cold weather just as crucial as when the sun is strongest in peak summer. The Crater Lake™ Heavyweight Half Zip has you covered with UPF 50+ sun protection, a full-coverage hood to shield your head, neck, and ears, HeiQ Mint anti-odor derived from plants, and a soft grid fleece backing for dawn patrol outings covered in cool morning dew. Wear it as a stand-alone top on shoulder season excursions or as a breathable baselayer for sunny, high-alpine travel.

  • Uses: Backpacking, Camping, Hiking, Ice Climbing, Rock Climbing, Skiing/Snowboarding, Winter Camping, Mountain Running
  • Full-length center front zipper
  • Two secure zip side entry hand pockets
  • Secure invisible zip chest pocket
  • Hem cinch at waist
  • Embroidered logo at left chest and left sleeve
