More than a base layer.... This is an insulating layer.

I love it! So soft and warm. I bought the coordinating pants as well and wore them the entire night I got them. I've got long arms and a long torso 5'8" 140lbs and the medium fit perfectly. I definitely want to get more. I get cold real easy and I noticed a big improvement in how long I stayed warm on the slopes.
Great ski top
I used this top in -13C weather in Austria and was quite comfortable. It's cute enough to pull on with jeans in the winter too.
