Customer Reviews Smartwool Classic All-Season Merino Base Layer Long Sleeve

Works great under my shirt. Use it a lot. Thanks

I use the 150 as a base layer for hiking as well as a base under a flannel for casual wear when it is cold out below 32. Incredible breathability and comfort and removes the moisture out when hiking hard so I never catch a chill. You get what you pay for and Smartwool is worth every penny!

Great

It's perfect for spring skiing and summer camping. The smooth flatlock seams and offset shoulder and side seams make it incredibly comfortable to wear all day long. I also love that some colorways feature a more responsible plant-based-dye technique. Overall, an amazing purchase that I highly recommend!

Great feel and quality. Works well as a base layer, obviously, but has a great clean look that you can wear anywhere. Fit is mostly great and true to size everywhere except the length which is much too long, which is annoying.

Great fit

Got for my son

nice design - great fit

Out of the box, this was really stiff/uncomfortable. After one wash it seems to be breaking down and kind of getting softer. Merino definitely feels different in the version compared to past year models.

Bought for a birthday gift. Awesome top for those cold temperatures. Warm and cozy!

Fits just right. Offers the flexibility and warmth needed. Love the Smartwool brand.

I have several base layer t-shirts and finally decided to purchase a long sleeve base layer. Excellent for all types of outdoor activities like snow shoveling or hiking

Excellent fit and feel and shipping.

The merino line is the best product out on the market today.. it is soft comfortable & warm! Smartwool has an amazing product line, keep up the good work!

Was not happy with the slim fit, it was like the slim fit T- shirt the shoulders fit great but way to tight in the mid section. But luckily my wife liked it so she wanted it for her walking.

Just an amazing product. Will buy more

Great product. Kept me warm on the mountain with just a shell jacket in 10 degree windy weather.

Love this base layer. Fits perfect and looks good!

This is worn everyday in the super cold climate we've found ourselves in. Also layered when outdoor activities are happening. Love it

These are great and they last a long time - finally had to get a few new ones after years.

Coming from synthetic base layers I finally understand how much better merino wool is. Regulates temperature in both hot and cold conditions.

The best single piece of clothes that I own! #sweepstakes"

Perfect layer for skiing

Sweepstakes I have been a longtime fan of Smartwool products These lighter weight base layers were exactly what I was looking for. Thanks Smartwool.

Either as a base layer in the cooler temps or alone on the warm days, these shirts are my go to.
