Sock Features

  • Hikes are better with dry feet — period. Our moisture-wicking merino wool blend keeps sweat at bay for long-lasting blister-free comfort.
  • Hiking in the summer doesn’t mean your socks have to stink. Our socks are naturally odor-resistant for high adventure odor control.
  • You don’t have to choose between comfort and durability - our socks have both. Made from soft, itch-free merino wool, they’re reinforced in the heel and toe.
  • Chilly mornings can lead to scorching afternoons, so we built a sock to handle either. Temperature-regulating merino wool helps keep those feet happy from dawn to dusk.
  • These socks have been thru-hiker tested on the Pacific Crest and Appalachian Trails.
