Sleep Better In Merino Wool.

  • Temperature-regulating properties mean you’re never too hot or cold.
  • Super-soft feel against your skin.
  • Won’t smell after weeks of wear, unlike cotton or synthetics.
  • Dries really fast, keeping you comfortable.
  • Folds up compactly, saving you essential packing space.

NATURE'S MIRACLE FABRIC

Every Merino wool fiber has a waxy coating called Lanolin, which helps wick moisture away from your body, and act as a safeguard against odor-causing bacteria. This is what allows our Merino to stay breathable and dry while smelling and feeling fresh, no matter what you put it through.

SOFTER THAN COTTON

This wool isn’t like your typical itchy sweater. We only use superfine Merino wool, resulting in a luxuriously silky soft feel that’s lighter and more plush than your average Merino or cotton. And unlike most clothes, it'll also maintain its form over time and won’t get ruined after a wash.

You won’t have to wash this pair of pants much at all. However, when it comes time for a refresh, simply add it to your load at the cold temperature setting and then lay flat to dry.

Can wear a dozen times without washing. Just hang on a hook to let sweat dry and it’s as good as new. This thing is magic.

    Sleep Set

    A beautiful sleep set! I am 5'3" tall, so the bottoms came to ankles, which I prefer anyway. I have not washed them yet, but have had great experience with Unbound Merino fabrics, so expect the same with this set.

    Great Pajama pants!

    Super soft, nice and flowy, great for lounging around in. And because of the style, wearing them lower on your waist means they’re long enough if you have a longer inseam!
