Review: Solid choice for a quality wool base layer. If you have a longer torso, get the mens version - I like to put wool gear to the test, wearing it for a week straight (washing if need be, at night, and letting it air dry overnight). I'm impressed at week one of wearing top and bottom under clothes. I've been warm, not hot, and although these fit closely, they are not snug. It's felt a bit like having my skin lightly massaged all day. Elbows (and knees in the matching bottoms) do show some stretching with multiple wears. I have both hand washed and machine washed on gentle cycle, tumble dry extra low. I think there will be some pilling in the future, but all in all, this feels like a solid base layer choice for multiple climates. I'm 5'2, 127lbs, medium boned with an athletic build. My husband is 5'8, 135lbs, small boned with an athletic build. The small women's fit me perfectly. The sleeves would come down a bit over my hands except for the weird cord like cuff- it would be exactly perfect with thumb holes. The shirt is close, not tight, and comes down to about mid hip, which is perfect for tucking in. The small men's fit me nearly perfectly - it was a little bit bigger, but not much, the main difference was that the mens version had a longer torso, which comes down over my bum. The mens small was a bit too tight on my husband and the sleeves were too short. The mens version also has soft, full cuffs. The women's version has almost like a cord around the end of the sleeves. Not a deal breaker, but I do find it irritating. Zoom in on the listing pics to see cuffs. Pros: Good quality Doesn't hold smells Temperature regulating Very soft - I've got super sensitive skin and this doesn't itch. The price is excellent Cons If you are tall, I'd suggest going for the mens version. This is perfect on someone short, like me. No thumb holes - I might even take it to a tailor to have thumb holes put in, as the cord makes it a bit uncomfortable to pull down over my hands. The cord like ending to the sleeves is annoying, I considered taking a star off for it, but the price and quality overall are so good that it didn't seem quite fair - more of a 1/2 star. I love that they sent a free pair of merino socks with each order (I ordered multiples for my husband and myself). The socks were much too big for me, but my husband was happy to restock his merino sock collection for free. (I'm a 6.5 - 7 shoe size, they were more appropriate for my husband's 10.5 shoe size) If I could give half stars, this would be 4.5 stars. It's a solid choice for someone transitioning to wool base layers. Honestly, the quality feels better than a lot of Smart Wool layers I've had, and it's softer.
Review: True to size, came with free socks! - This is a great, basic merino base layer that's perfect for my winter running in the Pacific Northwest. It doesn't make me feel obnoxiously hot even once I've racked up a couple miles (unlike my thicker or down layers, which I typically have to shed). Going by the size chart, I thought I might need to size up to a large, but desertcart recommended I go with my normal size medium, and I'm glad I did. I don't like oversized running stuff, and I hate when the shoulder and armpit seams are too large. For reference, I'm 5'9" tall, 158 pounds, athletic build, and the medium is great, with more than generous length in the arms and torso. Truthfully I would prefer a little bit less length in the torso, but I like things that hit just above my hips; after reading lots of reviews I've gathered that most women like things longer, so this longer length is likely better for most. This is what I would call a midweight layer, thin but not overly so, not something I would call ungenerous. It's exactly the right weight for the heat/insulation level advertised, and the temperatures I'm in right now (40s). I think it will also do well in the 30s. If it gets into the 20s, I think you might need to add a vest unless you're running very hard/hot. Included in the package was a pair of sweet thick wool socks. Love that unexpected bonus item! Just wish the socks were smaller; despite accompanying an order for a women's medium , the socks were large on my size 9.5 women's feet. Don't mean to be ungrateful, but dang! Matching the likely sock size range to the top size would be aces. Can't complain though, super happy with the fit and quality.

## 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/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. For a snug layering fit under jackets or ski gear, size down one

### ⭐⭐⭐⭐⭐ Soft, fits well very pleased
*by S***4 on July 13, 2026*

Just returned from the Scottish highlands where the temps were not above 58-60F and it was spitting rain almost everyday. I am always cold so I purchased this shirt to wear as a layer under my raincoat. I was never cold, in fact, I did get too warm and wore just the shirt with the sleeves pushed up. We did a lot of hiking however so I was moving. Had we been just walking around and not hiking, I think the combo could have been perfect. I am going to order a short sleeve one now but I figured Scotland would be cold and it was but the hiking was also intense. I am also VERY happy with the free socks that come with this shirt. I love them. They are thick and warm without being too warm and my goodness are they soft and not at all itchy. Highly recommended!
