Merino Base Layer - Dark Sapphire

45 reviews
    • Merino Magic

      Our Merino base layer constructed using Polartec's Power Wool is perfect for cooler days or big temperature swings. This soft fabric places lofted non-itchy merino wool on the inside for tremendous thermal regulation. The synthetic fabric face actively pulls moisture from the merino where it quickly wicks to your outermost layer. This keeping you at just the right temperature whether you're working out, Ornot.
      1. Made with Polartec Power Wool.
      2. Flatlock seams for comfort.
      3. 36% Merino wool interior / 64% polyester exterior.
      4. Excellent thermal regulation and natural odor management.
      5. Constructed with bluesign®-approved materials which conserve resources and protect the health of the environment, workers and you.
      6. Sewn by hand in California.

Merino sleeveless base layer

I highly recommend this baselayer. Very versatile, can be worn at almost any temperature. With just a short sleeve jersey a 60F start and 80F finish was completely comfortable. Use as a first layer for colder temps as well. I am 5’11” 147 and ordered the small.

Actually really great

It hasn't been cold enough to wear this as a base layer BUT I've been wearing it around as a tank and it's great. I'm a 5'4", 135lb. woman and the small fits me pretty well. I would say it rides up if I don't pull it back down appropriately but the seam around the bottom does a good job of keeping the shirt in place. I really like the blue as well. Overall, would buy again. Interested to see how it performs this winter.

Feels great and works perfectly as designed

Wearing this under an ornot lightweight long sleeve jersey with a vest and arm warmers is perfect for seattle spring. If I could wear one of these for every time under 70 degrees, I would.
