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 just received the 250 and 150 baselayers and both are baggy and way longer than previous models. Sizing inconsistency typi...

The Smartwool Men's Classic Thermal Merino Base Layer Crew is an outstanding addition to any outdoor enthusiast's wardrobe. From the moment I put it on, I was impressed by the softness of the merino wool, which feels luxurious against the skin. This base layer does an excellent job of regulating temperature, keeping me warm during cold weather while also wicking away moisture when I get active. One of the standout features is its breathability; I've worn it during long hikes and never felt overheated. The fit is great—it's snug but allows for ease of movement, making it perfect for layering under other clothing. I also appreciate the durability of the material; it holds up well after multiple washes without losing its shape or softness. Overall, I highly recommend the Smartwool Men's Classic Thermal Merino Base Layer Crew for anyone looking for a reliable and comfortable base layer for winter activities or everyday wear. It truly combines comfort, functionality, and style!

I have a few of them enjoy them all...the last one was an xl, same as all my others but definitely too big, that was disappointing. M
Good overall just a bit tighter than I expected.

Overall I like it, I did order one size up because I don't like form fitting clothing and it's still a bit tight but not so much that I wanted to send it back.
Great light weight solution to staying warm all winter!

I purchased because I wanted a wool base layer, so this item fir the bill. My original order came and both the bottom and the crew neck were way too big. If was not a contoured fit (slightly tight). The large was also a bit big, but a medium would likely be too small for my mid section... Customer service was great when I reached out about exchange/ return. Received new sizes before ski trip!

There is only one Merino base layer choice for me during the winter months in North Lake Tahoe's majestic Donner Lake community of Truckee, California. Be it skiing, dog walking or a rewarding day at work - I am always comfortable in my Smartwool.

Best garment purchase in 20 years! Slim sized, so I sized up. Wool might shrink a little with wash.
