Adore this top. It fits perfectly (I am 5'3" and 118#s), very snugly. It's an awesome base layer with a slight itchiness that I don't even notice any more. The sleeves are very long which would be good if the thumb hole was bigger. I have teeny hands and the thumb hole cuts my thumb off!

Bought this shirt in the Glacier/Smoke Small for my wife and it's functioning just as well (excellently!) as the 1/4 zip version that she has in Rose/Smoke. She tried this shirt on with a skin tone bra and it didn't show like the white bra in the picture. Excellent shirt fitted as a baselayer or a very athletic-cut single layer. My wife is a Small in Icebreaker stuff, XS in less athletic cuts of Columbia or REI.

Got the quarter zip last year, and wasn't disappointed with the new offerring. Got the guac/smoke and the color is great. Fit is great - nice length in the body and sleeves.

This is the second one Ive bought. last year I bought the one with a zipper. I wore it everyday while working outside on a ski hill. It NEVER stank (unlike capaline!)
I bought a second so I could switch It up a bit. Wash with your regular laundry, and your good to go! These are the only two tops i'm bringing for 21 days down the Colorado river.

Still a solid choice, but last year's version was a lot better. They are both long which is great for a base layer top so it is less likely to ride up, but this newer one is tighter in the hip/butt area which is not as functional for most women (hello people, women have hips!) so it tends to ride up a little anyway, despite the length. I have to try and stretch this one out a little before wearing it unlike the one I purchased last year which is still a perfect fit.

Last year's color choices were a lot better too, loved the charcoal one especially and do not like having such light colors in my base layers (this year's). It would have been nice to have one darker color option available. And normally I would be all over a green option, but that "guacamole" looks like vomit. Sorry guys!

To end on a high note, i still love the material and the weave they use. A nice flat smooth finish to this merino that is more like a jersey knit (but not as stretchy as cotton jersey) and good flat lock seems. And performance of the merino during activity is stellar.

this is a go-to shirt for me when I want something I can layer over a short sleeve and then tie around my waist when I heat up. I would size up if you want to layer it over things, or buy your regular size if you are wearing it alone. It is definitely a slimmer fit.
