This is the only piece of ski wear I use everyday. I have 4 skis, 2 boots, and I dont know how many jackets, but they rotate. This goes out with me everyday (well I have more than one, but same style)It never smells, is warmer than poly pro, and dries almost as fast. I love the thumb loops. I have base layers from UA, TNF, SW, and Marmot. This wins hands down.

The only gripe I could produce is it does come up high on the neck. I like that style, but on one jacket, if the base is zipped its tough to zip the jacket all the way. More of a defect in the jacket than it is the base layer. If you don't want something to come high on your neck, look at the crew instead.

After running a total of 14 miles in two days in both incredibly hot and cold weather, it keep me both warm and cool and was incredibly breathable! Definitely a quality top, a little expensive, but def. worth the money in the end!

I really love the fit, softness, and quality of the shirt but I don't wear it much due to the awkward turtle neck. It seems too long to zip all the way up, looks odd if you roll it half way down, and if you leave it unzipped, it does not have the rigidity to stand up on its own but also doesn't lie like it should if you fold it down. I love the shirt, but I wish I could get more use out of the thing. It's also my only shirt with thumb holes which is a plus.

Graet baselayeer for running,hiking,skiing,mountain biking,etc. in all kinds of weather. Recommended highly :-)

This is a great base layer top. The 1/4 zip offers climate control, and the merino wool offers all of its benefits. Wicking, warmth, and never stinky. I like the neck, and find it nicely sized. Definitely not made to fold over though. Somewhat pricey, but a very nice technical base layer. I would buy it again, and am considering buying a "spare".

Wool next to skin? Oh yes! I will never go back to polypro. This is soft, and makes polypro feel coarse and kind of plasticy. No smell? pretty true, at least It wont stink even after a day or two. It will smell, but more like you and less like BO, and less than a cotton shirt would smell. The thumbholes are nice in the cold, for keeping the undershirt in place when moving and reaching around a lot or even just to help when putting on your midlayer - but you dont have to use them, in fact the fabric is stretchy enough to push all the way up to the elbow. The high turtleneck is great if you are using it to stay warm - it will make a very easy and comfortable overlap with your balaclava. The construction is even nice enough to wear it just as a shirt so need to hesitate to strip down to just your base layer even in town. It is worth the price.
