  • Exceptional Comfort and Performance
Size: Small Color: .250 Charcoal Gray
I recently invested in the Merino.tech Merino Wool Base Layer Men's Set, and it's a game-changer. The combination of midweight, heavyweight, and lite options provides versatile comfort for various activities and temperatures. The merino wool material is a standout – it's incredibly soft, lightweight, and does an exceptional job regulating body temperature. Whether I'm out in the cold or facing milder conditions, this base layer keeps me comfortably warm without overheating. The attention to detail in the design is evident. The set fits like a second skin, providing a snug yet flexible feel that doesn't restrict movement. The breathability is impressive, making it ideal for both outdoor adventures and everyday wear. Durability is key for me, and this set has proven resilient to wear and tear. It's become my go-to for everything from hiking to chilly evenings at home. If you're looking for top-notch quality and performance, Merino.tech's Merino Wool Base Layer Set is a wise investment. Highly recommended! ... show more

  • Great quality, great fit
Size: Large Color: 250 Gray Heather
I took a chance on lower priced Merino and was pleasantly surprised. The fit is good, it's nice that they have a generous length. The fabric is soft and luxurious and I'm sure will be cozy warm when I wear it this winter. I missed the fact that they come with a pair of Merino socks. The socks are very nice as well. ... show more

  • Perfect weight, nice and long
Size: X-Large Color: Olive 250
Very nice sweater for layering or everyday wear. It's comfortable and very nice quality wool. Long enough in the body and arms for a 6'7" 225lb athletic build in size XL.

  • Nice fit, great base layer
Size: Large Color: 250 Windsor Blue
I wear this at work under a “scrub” shirt where room temperatures are about 65 degrees F. If necessary, a light jacket keeps me toasty comfortable.

  • Warmth and Comfort
Size: 3X-Large Color: .250 Charcoal Gray
Wool is one of those materials that will keep its insulative magic whether it is dry as it should be or even wet with rain. This particular wool garment is lightweight, but it is warm; moreover it is very, very comfortable. I’m a big guy, so I went with the XXX Lg, and it fits me perfectly. In the fall, I’ll wear it without any other top coverings, but in deep winter, it becomes an excellent base garment, added to my additional layers of wool, Underarmor, etc. So, yes, stay warm and stay comfortable. ... show more

  • Great value and quality
Size: Medium Color: 165 Black
I purchased 2 of the lighter weight merino wool long sleeve shirts for a layer during Winter golf speed training in my garage (MN Winter) and lifting and cardio in my basement. So far so good! Wicks moisture and keeps me comfortably warm. Regulates temperature to keep me warm but not hot. Just wish the body was a little more fitted as I am lean with broader shoulders and chest with slim waist. It checks all the boxes! ... show more

  • love these
Size: Medium Color: 320 Army Green
super comfy and warm. I'm 5'10 150lbs and wear medium. these are just a tad long in the sleeve and not skin tight but that's how I like it. probably could get away with buying a small. I've only washed it once by hand and there was some piling of fabric but other than that, I highly recommend these shirts ... show more

  • Merino wool thermal
Size: X-Large Color: 250 Natural Merinos
Super soft and warm. Doesn’t itch at all, even when you overheat and sweat! Skin stays dry and you’ll still be warm. Great product!
