Minus33 Merino Wool Woolverino Micro 1/4 Zip Men's Mock Neck - 84% Merino Wool, 12% Nylon, 4% Spandex

This is an awesome shirt. keeps you warm but still breaths. I usually wear a large but got the extra large and it fits me perfectly. It is super soft and comfortable and you can put it in the wash and dry it like a normal shirt! I'm in love and i will defiantly purchase more Minus33 products. Better than smartwool... life changing

The Amazon sizing chart is off for this product. The on-line chart lists 'Medium' as a 37-40 chest. ON THE MINUS33 BOX, medium is listed as 39-41, somewhat larger. That 'somewhat larger' is why I ordered a medium size. This being a base-layer garment, I wanted it to fit well...not tight, not snug, but not loose, either.Fact is, it's a tad snug, tight enough to chafe a bit under my arms with higher levels of activity. My next one will be a 'large' size (listed on the Minus33 box as 42-45). It is such a close call size-wise it is hard to say which will work better.As far as the garment itself: I came to Minus33 looking for a better quality item than what SW has become. SW costs a LOT more (maybe by 70%) and their quality has taken a dive over the years. Who wants to pay $100+ garment that falls apart in less than six months? Not me. And they (more than one) did. By comparison, Minus33 is a MUCH better quality article. I also prefer Minus33 over an ice breaking brand.If you are looking for a very good merino wool garment, give Minus33 a try.

One of my favourite clothing items, now that I stopped using Patagonia brand stuff. This shirt fits perfectly, feels great against the skin, and has held up to my less than friendly treatment. It wasn't cheap but you have to pay for nice things. Where I live near the Straits of Magellan this shirt is also a bit of a morale booster as well as essential clothing for the bitter months.

It feels lightweight and soft on the body. Until the weather deeps then I will know how well it can hold off cold as a base layer item.

I have not washed it that much and have worn it about weekly if not more and it has holes all over. Not from being caught on a zipper or anything else. The holes look like worn/weak places in the material itself. I won't order any other Minus33 items. I have another one almost like this one I ordered recently before I discovered the holes in this one and hate to think I will get holes in it too now. Very disappointed in this brand.

I have purchased several sets of Minus33 long underwear in various weights. I am 5'11" and 175 lbs and there fit like they were tailored for me. they are breathable so no matter what the temperature is your body is comfortable. They don't sag after wearing, they don't smell and I love them.

Merino wool in 17.5m is amazing stuff. Just about as soft as a nice cotton t-shirt and great against bare skin, yet with all the strangely perfect coolness and warmth of regular merino wool. What sets this one apart is the zipper and the price. It's cheap enough that it's okay to buy a bunch of them. The zipper makes it super versatile-- zip it up and it looks sleek and fairly dapper. Unzip it and it's ready for a hike. My only issue is that the fit doesn't just naturally fit me as well as Ibex stuff fits (plus, Ibex doesn't make a zip-T in 17.5m). But, at less than half an Ibex 17.5 t-shirt, it's a sacrifice I'm happy to live with.

Appears well made. Fits well. Time will tell how it holds up.
