The Gentoo is cut in a super soft and stretchy fabric made from recycled Nylon that will keep your stank and sweat in check. Easy to put on and take off (see: buttons), with thin mesh at the calves that’ll keep your socks in place and ensure there’s less bulk cramming up your boots. Finished with an easy-access butt-flap—a nod to the union suit of yesteryear, except streamlined with a hook-and-loop entry.

  • Power mesh below the knee to the ankle to contain your sock and create less bulk in your boot.
  • Button-down center front makes The Gentoo easy to get in and out of.
  • Gentoo’s butt-flap makes it easy for you to go to the restroom.
  • Two strips of hook-and-loop on both side seams so that you can adjust the coverage of the butt-flap to your comfort.
  • Extra long sleeves to make layering easy and lock in warmth.
