True to size, comfortable fit, but itchy. Don't consider myself the sensitive type but could not get over the itchy feeling of the merino wool. I own other top brand wool products but had have never felt the itchiness to this degree.
Bottomline, not for those that are itch averse.

First Ibex's stuff rocks.

Now this base layer is great compared to other base layers. Ultimately its a shirt so there is not too much variance within lite base layer shirts so while this shirt is great I wouldn't say is light years beyond anything else out there.

It is very light weight but Ibex's stuff is pretty rugged so I expect it to last a while. Its wool, my favorite, and not super itchy as merino of this price should be.

Fit is snug.

This is the best base layer I've ever owned. It's super light yet very warm and regulates temperature well. It's not itchy. It's stretchy and hugs the body well. It doesn't hold odors so wear it all week in the backcountry. My only complaint is that it's not made in the USA like some of their midweight base layers which, by the way, are also great.

I like its athletic cut, I like that it isn't itchy (though I don't wear it as a base layer- I put it over a capilene medium crew), I like that it's light, and I like that it's a natural material. All that said - this shirt is VERY warm. If you're going to be active, don't wear this unless it is very, very cold out. I live and play in Vermont and I wouldn't wear this for an aerobic activity if it were more than 10 degrees.

First off, let me mention that unlike many of the customers at this site, my cold weather gear is used for long treks to the bus stop, long waits for the bus, and long bus rides with no heat. I have about 0 tolerance for the cold. I am a librarian and have a need to dress appropriately (not looking like a homeless guy with 30 bulging layers) for the library, this requires thin and warm clothes. This shirt is awesome for all of the above situations. It is very comfortable to wear by itself around the apartment, whether or not the heat is working - it doesn't get too warm if the heat picks up, and it keeps me sufficiently warm when the heat (generally) does not kick on. I still haven't gotten the whole "wearing pants" thing down yet, though, so if they make similar leggings, that would be great. Also, it works well for shoveling snow - I wear this, a t-shirt, and a light jacket. It keeps me from overheating and freezing. Also, it comes in black, which is necessary.

I wore this shirt as a base layer 4 days straight during an urban winter outing in Detroit. It regulated temperature when moving from inside to out. The tight fit helped keep me warm, and the excellent wool kept me stink-free the entire time even after sweating it up in some over-heated buildings.

This thing is a fantastic base-layer, and sparked a whole new interest in wool clothing for me. I've worn it as a base-layer on the mountain and in a flag-football game in the rain... and it never failed. I was never cold, it amazingly regulated my body temperature, dry or soaked, and it doesn't get funky like the man-made fabrics do. A great product!

Not your itchy wool you’re used to. The finer wool fibers they use in the woolies crew make it just about as comfortable to wear as a normal cotton t shirt but with the added benefits of less odor and better wicking! This shirt has a trim fit so it fits snug.
