This is an awesome base layer for chilly weather! I use mine for backcountry research, and it goes seamlessly from a sleeping layer in 30-40 degree weather to being a great option for over a tanktop and under a fleece until the sun warms up. Fit is right on -- I'm a small, and a small fits perfect. Even a little loose so it's great over a tee or tank. Arm length is perfect, material is soft and wicks great. I bought this along with the MH Thermadry tights. A perfect combo. Blue's a great color too. Love all my MH stuff, and love your website. Free shipping and got here in 5 days. Couldn't be happier.

Wore a baselayer tank top underneath and my ski jacket on top--perfectly warm for spring night skiing in west virginia. comfy to wear around the house and for running too. i'm a little concerned about the material pill-ing in a year or so, but i think this is more comfortable than the silk-weight stuff.

Incredibly comfortable and the sizing was perfect. Prefer an xs for sizing across shoulders and chest, but they can run short - leaving my waist cold when the temps drop. This had enough length to cover me - and still look good!

I got this hoping to wear it over a t-shirt in the mild weather and under fleece in the cold weather. It does both nicely. It fits a little loose but that's how I wanted it to fit and it's heavy enough to wear on its own, but not too heavy.

I bought it because I moved to Norway and I realized that I needed some more warm clothes. It is does a great job of keeping me warm, but it is a little too big on me and I even went a size down (I got a small). The size is my only complaint; otherwise it is works really well.

Lightweight and very comfortable and fits wonderfully. Not tight and not baggy; looks great on any body shape.

Great quality. Good Lightweight layer for exercising/yoga, as well as in the lodge before and after skiing. Great for running and walking. Excellent wear and color.

This is a great piece! I love it for yoga - it breathes great!
