Don't bother with other thermals Honestly these are the best, I've tried many synthetic before and they fall short in comparison to these merino wool ones. They are soft, non itchy and durable. And most importantly they are natural fibers, we are exposed to so many chemicals and hormone disruptors it's nice to know a natural and efficient product to rival synthetic ones. Btw I tried them in my recent trip to Japan in -4 temperatures, life savers.

Megève, France 🇫🇷
-7°C to +5°C

Top-tier merino thermals and an even better seller experience. We bought a couple sets of 240 GSM Marino Wool base layers (leggings + long-sleeve tops) for our ski trip to Megève, France this Feb from Sleet.ae, and I couldn’t be happier. The seller was phenomenal; super responsive, extremely helpful, and lovely to deal with. They guided us on the right GSM options and even shipped “test fit” sets to try on and confirm sizing (a total game changer since most brands don’t allow returns once opened). Shipping was same day/next day, everything arrived earlier than expected, and the seller stayed in touch throughout with updates to ensure we were satisfied. They also included a large bottle of eco-friendly wool detergent, all included in the price. Performance-wise, these thermals were perfect. We wore them skiing/snowboarding and around town in -7°C to +5°C and stayed incredibly warm without ever feeling sweaty or overheated; just comfortable all day/night. They were so effective we could even ditch our mid-layers on the slopes. Perfect fit, comfort, and balance of insulation and breathability. I can’t recommend Sleet.ae enough, and I’m already looking forward to trying their 350 GSM merino thermals for even colder conditions.

Super quality I bought two white tops to wear under work shorts for a trip to London in November 2025. The morino didn’t show under the shirt (which was exactly the point). Also kept me very warm and more importantly I was walking a lot and did not experience overheating or sweating. Really great morino and would purchase more

  • What Does Micron Mean?

    • Wool softness is measured by the micron of each fiber. Micron refers to the diameter of the wool fiber — the lower the micron, the softer and finer the wool feels against the skin.
    • Sleet uses Superfine 18.5 micron Merino wool, giving it a soft, smooth, and comfortable feel.
    • To compare, a typical human hair is around 60 microns, which shows how fine and soft Superfine Merino wool really is.
  • What Does GSM Mean?

    • GSM (g/m²) means grams per square meter and measures the fabric's weight and density.
    • It does not always mean the fabric is thicker, because thickness depends on the fiber type and how the fabric is made.
    • Merino wool has an excellent warmth-to-weight ratio, so it can feel light while still providing strong warmth compared with cotton or synthetic fabrics of similar GSM.
