Merino Base Layer - Dark Sapphire

59 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.

It's merino. Thin , warm, no sleeves merino. What else is there to say?

Well made for daily use

Very good. Fits well -- Ornot runs "cyclist" in sizing so on the smaller end of any particular size's range. More fitted than club. More generous than, say, a Santini race cut.

I don't write reviews, but this undershirt is just so good, I'm letting you know.

Wonderful, just wonderful. The best product of its kind, in my experience.

Best next to skin layer

I have bought two; one for my husband 6’ 175 # Large and one for myself 5’8 155# Medium. We both agree that the fit is not too tight nor loose, it feels light against the skin and we live in Colorado so it is a go to staple most of the year. We do not wear it when it is temperatures over 85F or below 45F (we wear a little less or more, respectively).
