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

Perfect for our world cruise. Makes a perfect, long lasting capsule wardrobe for both my husband (73) and myself (64). "Active" has a different meaning at our age and ability. :)

These (and the short-sleeved counterpart) are the only shirts I wear. Nothing compares!

Some of the most comfortable material you can put against your skin

Great material! Warm but breathes.

I haven't had a chance to wear it for very long, but so far so good. Very comfortable.

Have not worn it yet but looks and feels great. Will be using on a trip to New Zealand in a week.

The shirt fit great and feels awesome. Perfect base layer and loved the color.

You can NEVER go wrong with a Smartwool Baselayer! Cozy next to your body and looking good!

Perfect lightweight year round comfort. My husband's favorite shirt, he buys 2 new ones a year.

I have 3 smartwool long sleeves of different insulating values This is the thinnest and its perfect for this time of year as it keeps u warm and cool , I bought this for a Colorado Bikepacking trip as it will protect my arms and body from the hot sun during the day and keep me warm at night as a base layer

Fell in love with this too from the first fitting. Feels so light, but does a phenomenal job at regulating temperature. I'm so glad that I had the foresight to purchase two of these shirts.

This is a great product. I use this for work in outdoor conditions. It keeps me warm and comfortable throughout the work day.

I honestly can't say enough great things about this top! The fit and feel are incredible. It doesn't itch at all. Temperature is regulated very well. I was thrilled from the first wear. Glad I bought two (a different color)

I wear around the house but also as a base for Spring snowboarding. It's so versatile!

Ideal for.. just about everything is a shoulder season camping/backpacking/hiking wardrobe. Liked the first one so much I got a second. Great weight for spring and will be ideal for summer at elevations.

Everyday base or single layer

Fits great and keeps me comfortable through a big temperature range.

Excellent any season lightweight top that seems to regulate the temperature quite well. As always, it delivers what I have come to expect from Smartwool: excellent quality, soft Merino wool, generous fit and the best customer support!

After buying one for myself, I loved it so much that I bought this base layer for my husband, too. It fits perfectly, feels good on, and keeps him warm.

Base layer. Base layer. Smart wool upped their game. Product is well made and keeps me warm in the coldest of weather.

Love the print.

I use it as a light base layer on chilly mornings. Not for very cold weather. Great weight Fabric. Runs a little small, but I want my base layer to be a little more fitted, so it works.

Great merino as always. A little tight in forearms, but otherwise, I'm confident this base layer will last quite a while and can be utilized from outdoors to the office

Warm and I look really cool.
