Smartwool Mid 250 Crew

Smartwool’s best-selling base, the Mid 250 crew is beyond comfortable and our primary pick for everything from cold weather casual use to winter camping. Below-zero skiing, chopping wood at the cabin, hanging out around the mountain town—this baselayer gets the job done. Plus, it’s definitely the best looking baselayer in the bunch—namely because it doesn’t really look like a baselayer, rather it appears to be a slim-fitting, comfortable long sleeve. The flatlock-seamed 100% Merino wool won’t chafe, even after being subjected to a jostling 65-liter pack for hours and is a top pick in cold weather conditions. Trust us, we know.

Tester Quote: “I wear this piece all the time, even as a long sleeve in moderate weather. I really appreciated the feel of the fabric; it’s a lot softer than any other baselayer I’ve tested. It wasn’t scratchy, it wicks well, and it looks great. That’s enough for me.
