Crafted from breathable alpaca, the men's Arms of Andes 160 Ultralight Alpaca Wool long-sleeve shirt keeps you warm and dry during intense activities—no matter the season or climate.


  • Made from fine alpaca wool fabric with cotton stitching and a cotton label—and zero synthetic fibers
  • Keeps you dry with sweat-wicking and low-absorption properties
  • Regulates body temperature, keeping you cool in hot climates and warm in cold climates
  • Naturally antibacterial and odor-resistant, helping it stay fresh so you can wash less
  • Alpaca fibers are naturally stretchy and form around the body without losing shape; slim, next-to-skin fit is designed to be functional and timeless
  • Wears well when hiking, tail running, camping and traveling in all conditions
  • Can be easily washed without felting
  • Wool is sourced using gentle shearing techniques from free-ranging alpacas that graze in the Peruvian Andes
  • From fiber to the finished top, everything is made in a single country
