I've had this shirt for about a year and half now. And I must say it's worth twice what I paid for it. I use it as a base layer outside in the cold and its works wonders. And as a top on its own when its just cool out (say 40+) It's so thin and the seems are so well done I can hardly tell I'm wearing anything at all. I will say I am a warm person in general, so a colder individual may not find it to be appropriate on it's own, but would make a great base layer.

I bought this for my husband who has been wearing the same ski stuff for a good decade +. I don't know how he was able to move with all the thick layers. Anyway, he was reluctant to trust that this shirt could keep him warm...and boy was he surprised!!! He loves this shirt. The fit is great, it does what it says it can do and he was toasty warm on a cold day up in Mammoth. Thanks for great service and another great product.

I wear this long sleeve shirt as a base layer all the time for running, hiking, or even just on a cold day. At first it seems like it would give little protection or warmth, but after you have it on and start moving, you realize how awesome it is. Even after constantly wearing and washing it, it still looks and feels brand new! I highly recommend this shirt!

Tight pits, thin fabric with no wind protection and little warmth.

The best base layer I've ever owned. I've used it skiing this year out here in Colorado on cold days and milder days (30's) and in both cases it performed great. It's also VERY comfortable.

Great wicking baselayer. A little skimpy, but performed perfectly as a lightweight base!

I use this as a baselayer while running, and really like it. It's very breathable, and often feels like I'm not wearing it at all! It also makes my rippling pectorals look great.
