This is a great shirt

I wear this under my hoodie everyday (I wash it regularly of course). I really like the style and comfort not to mention it performs better than expected. You know what I’m talking about- all those “performance” sweat wicking things and “keeps you warm while letting perspiration out” gimmicks we buy into and toss aside. Not this time around. This shirt really does have great comfort and performance- not too hot, not too cold. It’s just right for a base layer for when it’s chilly. I’m very satisfied with this particular purchase.

Thanks for this awesome review! We are glad you are enjoying the shirt!!
