Punti da controllare: vestibilità e taglia (meglio guardare bene la tabella), e lavaggio (seguire istruzioni per non infeltrire). Se la pelle è molto sensibile, la merino di solito è ok, ma può variare da persona a persona. In generale buon rapporto comfort/calore. Review: mejor de lo esperado - Increíble protección, resistente a humedad y no guarda olores , algunos sitios en internet recomendaban adquirir productos con un porcentaje de material sintético para evitar los olores, sin embargo este producto, 100% merino ha funcionado a la perfección para mantenerme cómodo y protegido del frío. 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. ## 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/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. For more relaxed fit order size up ## Customer Reviews ### ⭐⭐⭐⭐⭐ Caldo e confortevole, ottimo per freddo vero; attenzione alle taglie *by G***. on 29 January 2026* Completo termico in lana merino pensato per tenere caldo: ottimo isolamento e buona gestione dell’umidità, ideale per inverno e attività all’aperto.
