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/fall, 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 the weight you need **Q: Where does the merino wool sourced from and is this product certified?** A: Our products are made from New Zealand 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 if you prefer slim fit.

Pero es más cómodo de primera capa, que los conjuntos de sintéticos. ### ⭐⭐⭐⭐⭐ Excellent! *by M***D on 18 April 2026* I bought these with quality in mind and I was not disappointed. They are excellent in every way both warm and comfortable. Also with a free pair of merino wool socks as well. ### ⭐⭐⭐⭐⭐ Love it *by K***E on 7 February 2026* A better wait than the thin option. This one is holding up well but I did purchase a thinner one and it got holes within around 3 months of wear time. I love this blue color and it's vibrant and nice and warm --- ## 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.us/products/747540624-merino-tech-men-s-thermal-underwear-in-merino-wool-men](https://www.desertcart.us/products/747540624-merino-tech-men-s-thermal-underwear-in-merino-wool-men) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-05*
