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 ## 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.jp/products/382792944-100-merino-wool-base-layer-women-set-thermal-underwear-women](https://www.desertcart.jp/products/382792944-100-merino-wool-base-layer-women-set-thermal-underwear-women) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-14*
