Why We Like The Merino 250 Baselayer 1/4-Zip

When it gets cold, the Smartwool Merino 250 Baselayer 1/4-Zip is the top we turn to when the resort's extra cold. Being one of Smartwool’s heaviest merino baselayer options, it excels at thermal regulation in colder climates, and it reduces odor naturally for fresher comfort. Toss in the 1/4-zip functionality and we are equipped with a baselayer that gives us total control of our body temperature.

  • Merino wool adds natural odor-resistance
  • New slim-fit design for easy layering without additional bulk

Love this but with the zip for me it’s a second layer (over another SW simple base shirt). Great fit, fitted not skin tight.

Just a heads up- if you order charcoal heather it is NOT gray. It looks nothing like the picture they show, it is DARK and looks almost Navy/Black but not even close to what it shows so just FYI. I was bummed because I wanted a gray one

This was a replacement for a smartwool baselayer I'd been using for the last 5 years. Happy to have found the exact replacement. Perfect.

Very soft, conforming fabric with a little more heat than an Ortovox 185. Love the quarter zip for easy on off.

I took this out on the slopes on several days. Some days warmer than others. It is light weight but extremely comfortable. The zipper allows you to regulate the heat. I wore it two days in a row with no stink. Highly recommend.

Fantastic Baselayer

Great baselayer . Just the right warmth for Fairbanks Alaska. This top makes all the difference. Soft on the skin, isn’t irritating. Excellent investment

Defective Product And Poor Customer Serv

I purchased this product in Spring/Summer 2023 during a sale. I did not open the product until beginning of fall (purchased for a hunting base layer) to find the multiple holes. I immediately emailed returns and never got a response so about one month later emailed service. After back and forth for about 10 emails give or take (including photos fresh out of packaging) I received an RMA number to exchange the product (was offered money back or exchange). Upon receipt the return was declined due to 45 day window and the defective product is being returned to me. This took 3-4 months to figure out and backcountry's new response is to take it up with smart wool directly. Pretty disappointing experience with backcountry. I cancelled a larger black friday order due to this process. My other exact same shirt is great and will buy more, but won't purchase from BC again....

My girlfriend bought me this - my first wool shirt that I thought would be itchy - so I was hesitant. I now wear it for everything; an under layer, a workout shirt, a hang out shirt, whatever and whenever. Keeps me cool, keeps me warm, it doesn’t smell or stink and it’s wash and wear. I had her get me another one.
