2nd time purchasing this base layer

[This review was collected as part of a promotion.] I wear it during the winter to do most things - work from home, hike, grab coffee with friends. Its super functional and warm.

Great product!

[This review was collected as part of a promotion.] Nice fit. Keeps me warm on the mountain. I washed once to help with itchiness.

I have several and will continue to buy i

[This review was collected as part of a promotion.] I love the 1/4 zip mid weight base for both home use and hiking and/or snowshoeing. Having the 1/4 zip makes it easy to vent when I get overheated yet stay warm when needed when zipped up. I check smartwool every year to see what new patterns they have. I don't really want a plain one

Everyone needs at least 2 of these tops!

[This review was collected as part of a promotion.] One of my favorites tops to wear year round. Can layer with the crew underneath. Size media fits 8-10 well... size up if you want a looser fit.

I have just about every color!

[This review was collected as part of a promotion.] I live in my quarter zips all winter. They are great for layering. I love how soft they are, and how easily they wash.

Runs quite small but great construction

I've had these on and off through weight gains and losses, and myriad activities. Pleased to see the plus sizing as these run small and I order 1-2 sizes up to get a roomy fit & esp. a longer length. I wear these everywhere, from hiking and camping to casual work days, and am adding in a couple more to my rotation. Prior to the larger sizing being added, I tried switching to other brands and found they simply aren't as good. They're either thin and scratchy, or the elasticity doesn't last and they sag in a frumpy way. Smartwool is thick, soft and holds its shape.

I plan to add to my wardrobe

[This review was collected as part of a promotion.] Purchased originally for skiing but also took with me recently to Florida when weather turned a bit cooler and it was a life saver - while the thermal layer was warm I was not overheated Love it and and to plan to add to my wardrobe
