I purchased a small and was disappointed in the fit, if a XS is available and you're on the slim side I would get it. It is soft, and I love the selection of available colors.

...the title says it all. This shirt is good to sweat in. It's soft, comes in nice colors (I have it in Dark Raspberry and Glacier Green), and the price is pretty hard to beat. I will agree with other reviewers in saying the fit can be a little weird. I'm normally between a S and M in most things, and I got the S in this shirt. It fits well, but it's a little baggy by my armpits. At this price though, I'm not too concerned. It does the job and keeps me cool and comfortable while climbing, so I consider it a success.

The shirt is a nice color and great material. For me It was a weird fit. I ordered a Medium. It was too wide and hung funny on my body. The neck was also a weird width, it hit me mid shoulder. I thought I would try out Mountain Hardware since I like their gear, but the sizing is weird for my body type. I'm tall and lean/athletic. If it helps anyone brands that do work for me are Prana and Marmot. Great quality shirt, weird fit for me personally.

From the girlfriend:

I know some people like the super silky feel, but after trying the shirt on I decided to return it. Although it was pretty comfortable, I felt like it hung a little weird on my body and wasn't the most flattering fit. I ended up going with TNF's Reaxion Amp V-Neck T-Shirt. Nice technical shirt, but not the best for my taste in fit.

It's a fine workout shirt. I don't find it aesthetically pleasing, as it's shiny/silky and kind of a boxy fit. But, it's breathable and works well for exercising.

Nice looking shirt, and very comfortable. I've worn it to the gym and it's very lightweight. The length is great! Generally fits well, not very fitted which is what I was looking for but still has a pleasing silhouette.

gave as a gift " I got this shirt for running. It is great! I love the light weight material and it is very breathable. The fit is true to size.

Extremely light weight soft and silky feel to this shirt. Flattering fit and cut. Fits true to size. I wish it came in more colors. I weigh 133 lbs and am 5'5" and have an athletic build and take a medium, but I prefer a fit on the loose side, so the medium is perfect for me. I also always get medium in North Face. I hope my sizing comparisons help you!

Versatile shirt - very lightweight. and breathable. XS good for me, 115lbs and 5'5".
