  • Incredibly light and soft
Size: Medium Color: Deep Blue
This shirt is extremely lightweight and comfortable; great for hiking in a humid enviroment. It dries very quickly with no lingering smell like some performance fabrics. True to size. While I cannot speak for longevity (only had for a month), very pleased with performance, comfort, color and company. Easy to hand wash, air dries quickly. Great value for price. Started with purchasing one, ended up buying three for traveling , as it exceeded expectations! ... show more

  • Soft, Sturdy, and Powerful in a Power Outage!
Size: Large Color: Deep Blue
I am so thankful the folks who are responsible for the creation of this shirt! New England has been dumped with a couple of really nasty, heavy snowstorms this late March and April, in which hundreds of thousands have lost power, including me. Living in a building where everything is powered by electric, having a layer like this is really a true lifesaver. My skin is highly sensitive to friction, and although an alpaca gaiter completely failed, this t-shirt absolutely won the power outage! It is thoroughly comfortable: soft, well fitting according to the size chart, with absolutely no itchiness whatsoever. It truly is the perfect base layer in the cold, and I intend to purchase more for this winter. I chose to wash it upon arrival using a small drop of gentle unfragranced facial cleanser (it was what I had on hand) and a cold water soak of about 10 minutes. Following a thorough rinse also in cold water, I laid it upon a clean towel and gently rolled it to remove excess water. It's very important not to wring out wool, as it will stretch and harm the fibers. I laid it across the top of a drying rack, where it dried in about 18 hours. Had I done a second towel dry, it would have dried more quickly, but I hadn't planned well enough to do laundry so there wasn't quite an abundance of towels at hand! The result was a perfectly clean, cozy shirt ready to go. I checked all the seams and this shirt appears to be very well made and built to last. Wool base layers are supposed to be on the thin side, and that doesn't affect their warmth. Highly recommended! ... show more

  • T is ok, socks are great.
Size: Large Color: Black Ink
Honestly, I love Marino wool and wish I could have more but a t shirt, isn't exactly an item of clothing that works. It's a nice and comfortable t shirt, it does ok in the heat, but the real kill joy is the maintenance of it. It comes with an instruction care card, but honestly who has the time for that process (washing by hand, etc...). The socks that came with it though, are awesome! I'll buy more socks, but probably not the T. ... show more

  • Excellent quality and worth every penny
I had bought two of them about 6 months ago. I loved them so I bought 2 more a few weeks back! They are soft and light weight. They fit perfectly. I can't say anything negative about the product and I highly recommend them for anyone.

  • Excellent shirt
Size: Medium Color: Melange Black
This shirt is super comfortable and the stitching appears to be good quality. The feel is super soft and not itchy at all like I thought it might be. I liked the shirt so much that I ordered a set of their base layers as well. Great brand, I will definitely get more of these shirts. The socks that I received were a size Large (but I received a Medium with my base layer set, so they might be random). I can't say the socks are my favorite and they're a bit itchy. I think Costco's cheap wool socks are nicer. Since I didn't order this for the socks so this won't be reflected in the rating. ... show more

  • Perfect for hiking in El Salvador
Size: Large Color: Black Ink
No joke. That's where I wore this. Also in London during a humid heat wave. The shirt stands up to sweat really well and never stinks. Never. I wore it for five days in the jungle while hiking with a group of family and friends. I never smelled bad at all, and my husband would have told me. I never had to wash it, until I got home. It dries overnight if you choose to wash it, and comes out slightly wrinkled, but once you stretch it a bit it smooths out. It is counterintuitive, but the Merino wool keeps you cool, since the weave is not super tight, so the ventilation is very good, and it seems to wick moisture, as well. Great product, and would buy it again. ... show more

  • Good quality but ...
Size: Large Color: Black Ink
The tshirt fit well and seems of good quality. The listing on Amazon included free socks. Okay a single pair of socks. However I must have missed where it was redeemable after applying and then I received a code to separate order the socks. Shipping was almost the proof the socks, so not free...

  • Soft, comfortable, but be gentle!
Size: Large Color: Deep Blue
This shirt is extremely soft! It’s not quite as well made as my Icebreaker merino shirt, but it’s still a great shirt. It did develop a hole in the sleeve after the first week, but Merino Tech stood by their product and sent me another shirt free of charge. I’m very hopeful the new shirt will hold up, because I really enjoy wearing it!! In fact, I took it to Ireland with me just a week and a half ago. It was a perfect travel shirt. ... show more
