  • Enjoy your post-hike high even more with socks that don’t stink. Cloudline socks are naturally odor-resistant and keep odors under control.

  • When you’re chasing the cloudline, the weather can change on a dime. Our temperature regulating merino wool blend ensures your feet stay comfortable all day long.
  • These socks have been thru-hiker tested on the Pacific Crest and Appalachian Trails.
