Il est confortable, tient chaud et permet de mieux supporter cette frilosité. Je suis content de mon achat. Une paire de chaussettes était présente. Je ne peux me prononcer, je n'ai pas testé.

## Questions & Answers

**Q: Won't merino wool feel itchy? 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

### ⭐⭐⭐⭐⭐ Ultimate Cold Weather Armor – Exceptional Wind Defense and All-Day Dry Comfort
*by A***M on 27 June 2026*

Finding a high-performance thermal base layer that effectively seals in core body heat without bunching up under heavy canvas canvas pants or causing you to sweat during high-exertion tasks is critical for northern survival. Most synthetic thermals trap moisture against the skin, leading to a dangerous rapid chill the moment you stop moving. These 100% Merino Wool base layer leggings from Merino.tech completely reset the baseline for premium winter work gear, acting as a non-negotiable barrier against severe conditions. They are absolutely perfect for my working outdoors in Canadian winter cold and wind. Premium 100% Merino Insulation Matrix: The absolute triumph of these leggings is the pure merino wool construction. Unlike scratchy traditional wool or cheap polyester blends, this fabric delivers an incredibly soft, lightweight, and high-density thermal grid. It breathes beautifully while simultaneously trapping an insulating layer of warm air right next to your body, blocking out biting, sub-zero prairie winds and sub-freezing temperatures effortlessly during long hours on an open job site. Moisture Logistics & Ergonomic Fit: Merino.tech has engineered this piece with excellent moisture-wicking properties. If you are lifting, loading, or moving actively, the fibers draw sweat away from the skin instantly, keeping you completely dry and preventing post-activity hypothermia drops. The flat-lock seam architecture and elastic waistband provide a secure, friction-free fit that moves naturally with your body, ensuring zero chafing or restrictive pulling when wearing heavy-duty work boots and layered outer shells. Pros: 100% pure merino wool provides elite, natural thermal regulation and wind defense. Advanced moisture-wicking dynamics prevent damp chilling during heavy physical labor. Flat-lock seam construction completely eliminates inner thigh chafing and hotspots. Outstanding natural odor resistance keeps the fabric fresh over long shifts. Cons: Because this is a premium, pure natural fiber garment, you must wash it on a gentle cycle and hang it up to air dry rather than tossing it into a high-heat commercial dryer to avoid accidental shrinking! Verdict: A flawless, high-utility industrial safety asset that completely transforms how you handle brutal winter weather. If you work outdoors in extreme elements and demand heavy-duty, reliable, and comfortable warmth, these Merino.tech thermal pants are a mandatory wardrobe upgrade.
