Very Satisfied with this Base Layer
I have several of these Smart Wool 250s to include some zip styles. I have been extremely satisfied with these shirts. I wear them next to my skin with an additional layer or two depending on how cold and the weather may be here in Colorado. I do not ski or snowboard, however, these shirts work g...

The fit has changed!!!
I've been an avid smartwool person for years and wear it in some capacity almost daily. The baselayers have always been cut so they form fit as specified by the "slim fit".

I would absolutely buy this shirt again
This shirt is soft, not at all itchy and wonderfully warm for our cold climate and inability to stay warm in our advancing age.
My go-to for winter base layers
I've been wearing the classis wool base layers for several years because they keep me warm in the cold MN winters. The reasons I've been sticking with them is that they are the most comfortable and warm and the fact that they are 100% merino wool. I wear them for skiing, walking the dogs, hiking, and basically any activity outdoors in the winter. I own multiple pairs of tops and bottoms and wear them every day during the winter.

We love hearing from brand fans like you! Thanks for the kind review.
Great for golf
Base layer while golfing in 40-50F weather. Kept me warm in the morning chill. And wicked away the sweat when it warmed up a bit. Awesome piece. Want a bunch more.
