This top is gorgeous, and practical as well. I am 5'4" 118# and bought a small, which is just right-not tight, but very flattering. The salsa color is really beautiful, and the fabric is extremely comfortable.

I am a converted merino wool wearer - highly recommended this one for cooler weather running. Very breathable and I love the bright color. The fit is very comfortable, not tight, definitely a 'must have".

Love this... wore it running the day I got it. Fits perfect and performs great! Love the color, super soft and breathable, love the side pocket and thumbholes too. 5'6" 125lb, and small is perfect. It'll be a good baselayer in the winter too.

I am 5'8 140lbs, and have a large. I like my shirts a little on the roomy side and this one feels great. However my only real complaint is the thumb holes... way small and hurts when I am bending over to tighten my bindings, or out stretching. Other than that I will always use this shirt as a base when going out on cold blowy days. Its super warm and wicks sweat very well. I have toured in this shirt and been too warm.. so think about that..

Great top - I ordered the xs (5'6, 103lb) and it's perfect. A slim fit, but definitely room to move (not any of that spandexy, Saran-Wrappy feel). It's great for bouldering, hiking, and just hanging out. The merino wool is super soft (not itchy at all), and it really does not hold odors, which is basically a miracle after wearing polyester shirts that hang on to sweaty smells like it's nobody's business. I never use the side pocket, so I could definitely do without it, but it's fine - I still love the top.
