Happy
Yes , I recommend this product
Smartwool, Love It!! I wanted a medium to heavy weight second layer. I settled for the Smartwool Intraknit 1/4 zip base layer. I am happy with the warmth it generates just by itself. With a jacket or parka over it is great. Selecting the larger size was a good decision, Intraknit is true fit, snug. I am happy with my selection.

Versatile Base Layer
Yes , I recommend this product
This quarter zip makes a great base layer for skiing, but is also great to wear with a pair of pants for a casual event. It fits close to the skin, but is not too tight. It's a beautiful shade of blue with some subtle details that elevate the look.
