Runs slightly big but I prefer this for hiking and layering. I’m 5ft and the leggings run long, easy to roll up though. Quality is excellent and overall it’s good value for money and merino wool is the best for keeping you warm! Review: I purchased the Merino Tech 100% merino wool thermal sets (320g, charcoal gray) for both my mother and father, and they absolutely love them. Truly—love them. Before this, I had always sent them synthetic thermal underwear (polyester-type fabrics), which were fine, but after discovering Merino Tech, I realized what a huge difference natural merino wool makes. This is a complete game changer. The fabric is incredibly soft, smooth, and gentle on the skin. My parents immediately commented on how comfortable, warm, and luxurious it feels. It’s not itchy at all—just cozy, breathable, and beautifully made. On top of that, the design is stylish and flattering, which is rare for thermal wear. They look good and feel great wearing them. What impressed me just as much was Merino Tech’s outstanding customer service. I had a discount code that I forgot to apply at checkout (which is totally my fault), and most companies would simply say “sorry, we can’t do anything.” But the Merino Tech team was incredibly kind and generous—they honored the discount after the purchase and refunded the difference. That level of integrity and customer care is rare and deeply appreciated. I also love that merino wool is a natural fiber. It feels healthier, more breathable, and more aligned with the body than synthetic materials. You can genuinely feel the quality. I am so happy I chose Merino Tech for my parents. It was a gift that truly made a difference in their daily comfort, and that means everything to me. I highly, highly recommend Merino Tech to anyone looking for premium, natural, and beautifully made thermal wear. ## Features - Medium — Women's Merino Wool Underwear Available in: Light = 165 g/m², Medium = 250 g/m², Heavy = 320 g/m².

And what does 17.5 micron mean?** A: 17.5 micron superfine merino fibers are finer than human hair — too fine to feel itchy, even on sensitive skin. Standard wool (25+ microns) causes irritation; this doesn't. OEKO-TEX certified, tested against 100+ harmful substances. **Q: How do I wash and dry it to keep it looking new ? Will it shrink or lose shape?** A: Machine wash cold max 30°C, delicate cycle, inside out. Lay flat to dry — tumble drying permanently damages merino fibers. Store clean and dry; keep merino in sealed bags to prevent moths. Wear 3–5 days between washes — merino resists odor naturally **Q: Which weight should I choose — 165, 250, or 320 g/m²?** A: 165 g/m² — active pursuits, travel, spring/summer, 40–60°F. 250 g/m² — cold weather, most outdoor activities, 25–45°F. 320 g/m² — frost and low activity, 10–35°F, extreme conditions. Rule: the higher the activity level — the lighter weight. **Q: Where does the merino wool sourced from and is this product certified?** A: Our products are made from Australian merino wool, RWS certified — independent farm audit confirming animal welfare and land management standards. Every component tested against 100+ harmful substances under OEKO-TEX Standard 100. **Q: Does it fit true to size?** A: Choose your regular size. For a snug layering fit under jackets or ski gear, size down one ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***9 on 31 January 2026* I bought this set for a trip to Iceland and wore for 3 consecutive days in cold conditions.

Nachdem ich mich stundenlang mit Merino Unterwäsche beschäftigt habe, landete ich letztlich bei dieser hier und ich bin mega zufrieden. Sie ist total warm, angenehm auf der Haut und schön lang. Für mich mit 1.80 perfekt. Ich bin sehr schlank und hätte wahrscheinlich von der Breite her auch in eine S gepasst aber ich finde die M passt perfekt und ist nicht zu eng. Und dann gibt’s auch noch Socken dazu! Ich kann die Unterwäsche nur empfehlen! ## Frequently Bought Together - Merino.tech Merino Wool Base Layer Women Set - Heavyweight, Lite, Midweight Merino Thermal Underwear For Women Top, Bottom - Merino.tech Merino Wool Base Layer Mens Set - Heavyweight, Midweight, Lite Merino Wool Thermal Underwear For Men Top, Bottom - Merino.tech Merino Wool Base Layer Women - 100% Merino Wool Heavyweight, Midweight, Lite Long Sleeve Thermal Shirt and Socks --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/386836077-merino-wool-base-layer-womens-set-midweight-merino-wool-thermal](https://www.desertcart.com.ar/products/386836077-merino-wool-base-layer-womens-set-midweight-merino-wool-thermal) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-07-28*
