I love this! it keeps me so warm and is easy to pull down to pee. The only thing is that i wish the bottom zipped all the way off instead of 90%. I stay super warm and it is the only thing i have been wearing under my snowpants and coat!!! I am 115LBS 5'4'' and the medium fits perfect in my legs but a little baggy on the top, but it's nice i can put a layer under the top and over the bottoms. The blue is super cool! LOVE LOVE LOVE!
