Looovvveeee it

LOVE this base layer!!! On the thinner side, but kept me warm on the slopes with the highlander hoodie over it. Extremely soft, extremely comfortable. I’m typically a medium or large, and went with a medium. Maybe size down if you are in between sizes.

My new favorite baselayer! It's the most comfortable one I own, keeps me warm and dries quickly.

This is a well made garment but it is too loose for a base layer. I use this when I play golf and it would keep more heat in if it were tighter. I have a lot of Uniglo heattech and they fit great.

I was underwhelmed by the product. Amazing how many people rave about this pullover but although soft and comfortable it was too thin, not warm at all and the price point is higher than I would pay again for this.
