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 the 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 if you prefer slim fit.

He estado por una hora en un bote en el ártico (tour para ver ballenas) con rachas de viento que han bajado por instantes el termómetro a -30 y sin notar frío, eso sí, con sistema de capas y la opción de 320g, con la de 250 he notado claramente la diferencia, y supongo que sería la ideal para actividades en la nieve, o caminatas por ciudades moderadamente nevadas. ### ⭐⭐⭐⭐⭐ My go-to long Johns *by on Reviewed in the United States 13 September 2026* Excellent long Johns! These are cozy and warm. Snug and great fitting but breathable and moisture wicking. The merino wool is soft and not itchy. I think the mid weight is ideal for almost any outdoor activity as a base layer. Wear these hunting, hiking, skiing, ice fishing, under your waders, under snowmobile suit, under cover alls. If you live or work outdoors, these are for you. Well made. Great quality. Accurate sizing. Good value. ### ⭐⭐⭐⭐⭐ Warm with perfect fit *by on Reviewed in the United Kingdom 6 January 2026* Have this for year now and used it extensively! They are durable and warm. Highly recommended! Excellent value for money. ## Frequently Bought Together - Merino.tech Merino Wool Base Layer Mens Set - Heavyweight, Midweight, Lite Merino Wool Thermal Underwear For Men Top, Bottom - Merino Wool Base Layer Mens Bottom Pants 100% Merino Wool Heavyweight, Midweight, Lite Thermal Underwear Long Johns and Socks - Merino.tech Merino Wool Base Layer - Mens 100% Merino Wool Long Sleeve Thermal Shirts Heavyweight, Midweight, Lite with 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.pe/products/744100881-merino-tech-merino-wool-base-layer-mens-100-merino-wool](https://www.desertcart.pe/products/744100881-merino-tech-merino-wool-base-layer-mens-100-merino-wool) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-10-29*
