Power Stretch is the BEST!
I feel the discovery of Power Stretch clothing is the best invention for all of us...ACTIVE & sports orientated people of all ages. Not only it stretches in every direction, it protects me from freezing in cold weather with temperatures range from sub-zero up to between 40-50 degrees (works for me). I love it so much that I am on the lookout for more different colors sometime in the fall. Worth the money and I'll buy it again in a beat!

Great top!
This top is very functional and technical top. I have few of this top in different colors and love it. It is so cozy and warm against your skin. This year I wore it few times under my ski jacket on a cold and breezy day. I was surprised how warm I was without the bulk. In the lodge it was very stylish by itself.

the best all rounder and my GO-TO top
i have every version of these powerstretch (hoody, full and half zip) and they are the best for temps ranging between 20-70 either as an insulating mid-layer or top layer. love love love how light they are, no pinching or binding or bunching of fabric, and warmth to weight ration is off the charts. only complaint, they pill relatively quickly.

Marmot Womens Power Stretch half zip
Great fit and fabric. Perfect for winter sports; Warm without bulk. Highly recommend!!!

Nice
Bought this to wear to work. I am a cop in WI and the winters can be brutal. Hard to find functional clothing for women that is acceptable in work setting (IE black). I wear this under tactical vest, shirt, and sweater and am toasty. Wish the sleeves were a tad longer. I also train dogs in herding all year long, and can wear this during training as well and I am comfortable. I am not crazy about the outside texture of the garment and I am having some issues with the zipper. Overall, it is warm, can be worn inside, outside, it's versatile, and a good investment.
