    Engineered Layers So You Can Go Further

    It’s pretty simple: when your gear works better, you can stay out longer. Instead of looking at layers individually, we took a “system” approach – designing pieces that not only work independently, but together as well. Fitting together. Made for each other. Smart layers that are more efficient, with less bulk.

    Layered together, our system doesn’t bunch or restrict movement, so you can focus on your adventure, not your clothing.


    Machine Wash Cold Gentle Cycle. Turn inside out before washing.

    Do Not Bleach. Bleach damages the natural wool fiber.

    Tumble Dry Low. Lay flat or line dry for best appearance.

    Iron Low. Hot irons can scorch the fabric.

    Dry Clean. Professionally dry clean as necessary.
