Customer Reviews Smartwool Merino 250 Base Layer Crew

My boyfriend loves his smart wool base layer and it regulates the temperature to handle chilly days but he doesn't overheat when it's warm either! A high quality, long lasting piece to own.

Got this for my boyfriend as a Christmas gift as a base layer for outdoor work, and he had hardly taken it off since. He says it's super-comfy and warm, and obviously the antimicrobial qualities are working because he still smells great

These are my husband's favorite tops! They work alone as sweaters on mild days and work well as base layers in the cold weather. They wash well on a normal cold water setting (no need for delicate cycle was) and dry beautifully on a low setting. They are well made and last for years!

Great shirt and warm!

Great product!

Use them for biking, hiking, skiing. Any the big outdoors when it gets cold

The color is perfect. This is a staple for me when hunting

I wear these when the temperature drops below-15 C. I have two other sets, wanted a couple more in the rotation. The Smartwool shirts are higher quality and warmer than my other Merino shirts.

Perfect for snowmobiling

Excellent, my husband loved this base layer shirt.

I use this to ski, hike, and bike. Comfortable fit, and keeps me warm and dry.

Got this for my husband for winter sport, fits well and comfortable with small itchy as expected.

Great size and lightweight but also super warm.

Comfortable and stylish. Can wear as a base layer as well as a shirt.

Fits true to size. Great quality.

Great base layer. Thin enough for good mobility and very warm.

It's my everyday undershirt base layers. Super comfortable and it can worn multiple days too as they don't stink after a days use.

Outdoor work and snowboarding base layer.

These are part of the daily wardrobe in winter. Never too hot, always comfortable. Biggest decision is which color to wear.

Love the color, fit and quality!

Purchased for my son. He was super happy to have comfortable, well working layers for the mountains & other adventures.

Amazing base layer, comfy and warm.

I have to wear a winter hat and have bought a few. This one is soft and fits very comfortably.

Incredibly comfortable, super warm, and the fit is spot on. I'm never disappointed with anything from Smartwool

I love that these are all-natural - no synthetics!
