Wear them all the time in the winter during the day and to bed as "pajamas". Comfortable, fit great, do not collect odor, keep my legs warm but not too warm. Review: Well made, warm, good fit, cozy - It's really nice being so toasty warm and feeling so cozy like I'm in my pajamas when I'm out in my work clothes. Super soft 100% merino wool thermals feels so good and soft against your skin. Very functional and I really appreciate that they're not too loose to be baggy and not too tight so the fabric doesn't pull on my leg hairs and is not itchy at all. I didn't know how warm they would be and considered the 250 gm. but I'm really glad I got the 320s because they're not too warm for up north where I am. I do have several shirts of different weights so I can layer to whatever warmth I need and stay warm with just a heavy sweatshirt over them in the northern winter. That's a lot of great value for such reasonably priced, sturdy and durable feeling, odor free, 100% merino wool! I highly recommend merino.tec 320,100% merino wool thermal base layer. You won't be disappointed! ## Features - Midweight: Mens Merino Base Layer Available in: Lightweight 165 g/m², Midweight 250 g/m², Heavyweight 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/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. For a snug layering fit under jackets or ski gear, size down one ## Customer Reviews ### ⭐⭐⭐⭐⭐ One of my best buys ever! *by C***Y on April 6, 2026* Great product! Wear them all the time in the winter during the day and to bed as "pajamas". Comfortable, fit great, do not collect odor, keep my legs warm but not too warm. ### ⭐⭐⭐⭐⭐ Well made, warm, good fit, cozy *by R***S on November 27, 2024* It's really nice being so toasty warm and feeling so cozy like I'm in my pajamas when I'm out in my work clothes. Super soft 100% merino wool thermals feels so good and soft against your skin. Very functional and I really appreciate that they're not too loose to be baggy and not too tight so the fabric doesn't pull on my leg hairs and is not itchy at all. I didn't know how warm they would be and considered the 250 gm. but I'm really glad I got the 320s because they're not too warm for up north where I am.

That's a lot of great value for such reasonably priced, sturdy and durable feeling, odor free, 100% merino wool! I highly recommend merino.tec 320,100% merino wool thermal base layer. You won't be disappointed! ### ⭐⭐⭐⭐⭐ Warm, and Good for Layering, and Great for Cold Rides! *by C***R on April 30, 2025* I picked up the medium black 250 and it’s been perfect for cold weather riding and chilly workdays. I’m 5'10" and 180 lbs, and while the fit is a bit loose, the length is perfect. After 2 years of regular use, it’s still going strong—just a minor hole at the ankle, easily hidden by socks. Pros: ✅ Great Cold-Weather Warmth (250 Weight) – Warm enough that I haven’t needed to upgrade to 320 ✅ Ideal for Motorcycle Rides & Cold Work Days – Keeps me warm without bulk ✅ Socks Are High Quality – Cozy and well-made ✅ Durable Over Time – Still in good shape after 2 years Cons: ❌ Slightly Loose Fit (Medium on 5'10", 180 lbs) – Not overly baggy, just not snug ❌ Minor Wear – Small hole near ankle, but nothing major Final Thoughts: Whether you’re riding in the cold or braving freezing temps at work, this base layer does the job exceptionally well. Warm, breathable, and built to last—an excellent investment for cold-weather comfort. ## Frequently Bought Together - 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 - Merino Wool Base Layer Women Pants 100% Merino Wool Leggings Heavyweight, Midweight, Lite Thermal Underwear Bottom 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.tn/products/257159471-merino-wool-base-layer-mens-bottom-pants-100-merino-wool](https://www.desertcart.tn/products/257159471-merino-wool-base-layer-mens-bottom-pants-100-merino-wool) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-07*
