I already owned one of these shirts which has served me well through trips to Alaska, and various hiking and travels all around the country. It is my go-to base layer. It looks nice on its own, and absolutely serves its purpose under any type of clothing. It keeps me warm when it’s cold and nice and cool when it’s warmer. The best part is that because of its wool qualities it stays in great shape even between washes! I wore it several different days during a cross country road trip and after setting it out at bedtime, by the next morning it was fresh as new! That is my favorite quality about merino wool! It is soft and not itchy, trim and not bulky, and keeps me warm while still being breathable and never too hot. I am such a fan of this brand and will probably buy even more so I can wear them more on the daily (instead of just as cold weather/hiking/traveling wear). I definitely needed to get another one so I bought this set because what a deal to get not only the shirt and pants but also the hat and socks! All set now! I will note that these do run a bit large. I am usually around a M/L in size, after reading the comments when I bought my first shirt I bought a M and it fit great! It was fitted with a bit of room to spare. When I bought this set, seeing as it comes with bottoms (I am a true L in bottoms) I bought L this time to try it out. It was a bit baggy and quite roomy. Would make for great pajamas! Maybe a little too loose for base layers or on their own. If I were to buy another pair of these I would def size down again and get M for both top and bottom. Overall, I am so happy with this brand and highly recommend! Review: A Gift That Truly Made a Difference - I purchased the Merino Tech 100% merino wool thermal sets (320g, charcoal gray) for both my mother and father, and they absolutely love them. Truly—love them. Before this, I had always sent them synthetic thermal underwear (polyester-type fabrics), which were fine, but after discovering Merino Tech, I realized what a huge difference natural merino wool makes. This is a complete game changer. The fabric is incredibly soft, smooth, and gentle on the skin. My parents immediately commented on how comfortable, warm, and luxurious it feels. It’s not itchy at all—just cozy, breathable, and beautifully made. On top of that, the design is stylish and flattering, which is rare for thermal wear. They look good and feel great wearing them. What impressed me just as much was Merino Tech’s outstanding customer service. I had a discount code that I forgot to apply at checkout (which is totally my fault), and most companies would simply say “sorry, we can’t do anything.” But the Merino Tech team was incredibly kind and generous—they honored the discount after the purchase and refunded the difference. That level of integrity and customer care is rare and deeply appreciated. I also love that merino wool is a natural fiber. It feels healthier, more breathable, and more aligned with the body than synthetic materials. You can genuinely feel the quality. I am so happy I chose Merino Tech for my parents. It was a gift that truly made a difference in their daily comfort, and that means everything to me. I highly, highly recommend Merino Tech to anyone looking for premium, natural, and beautifully made thermal wear. ## Features - Midweight: Womens Merino Base Layer Set 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 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for so many occasions *by A***H on January 31, 2025* This was an awesome deal!
