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

Love this as a thin base layer- I can wear it under a lot of layers, or with fewer on a warmer day. #sweepstakes

I have had these base layer shirts in my wardrobe for years. I'm a repeat customer (new color this time) and will always be.

Great shirt to wear alone or as a layering piece. Usually wear a small or medium and purchased a small.

Comfortable and good fit. Like the feel of the material.

I actually did order the same color twice! Twilight Blue Heather

Great winter base layer for Wisconsin winter runs.

Repurchased after owning and wearing for years as a hiking shirt and/or base layer. Love the eggplant color.

Washes and dries really well. Great base layer under fleece or sweater. Getting ready for trip to Iceland and purchased a second top after I wore the first one.

I own lots of Smartwool. I use the heavier thermal for outdoor activities; however, I own 4 "all-season" crews that I wear under shirts/sweaters in the winter to keep me warm all day. They wear and fit well, don't pill, and do not absorb odors. They are fitted, but not tight. My whole family wears Smartwool because we like the function and the look.

I wear these everyday to work. They are comfortable and keep me warm. I love the feel of the material. I love all smartwool products! I tried to leave 5 stars but it would not highlight the last star.

I bought for camping in the Smokies for March. I've been wearing these in the house on chilly days and want to purchase more happy colors.

Great as athletic or daily base layer. Light weight so good in shoulder seasons too.

Love for quality and comfort. Worth knowing what I'm getting.

I've been wearing Smart Wheel products for many years and will continue to wear them for many more. I love all of the products that keep you warm and dry.

Purchased as a Christmas gift. Fits perfect

Great for in between seasons.

This shirt fits great and I'll be wearing it with jeans on a regular basis!

Material is about the same thickness as a t-shirt and looks like a long sleeve t-shirt on. I just wish it were a little more stylish and cropped.

the green color is nice but it will really show-off your underarm sweat during activities, so keep that in mind for your use case. as with all smartwool, sweat will dry out even while you're still wearing it.

Wife likes the fit and the material texture. Will use it on the upcoming Iceland trip.

I ordered this thinking I had the all season base layers and was adding colors. Very disappointed as this is very thin/transparent. Not all season where I live. Definitely need to layer it with another layer. The Thermal classic base layer is soft and can be worn alone 3 seasons. Oops order.

This is a base layer to wear when i am outdoors in the cold.

I actually sleep in these. Ideal temperature for me. Great base layer works best when it is the first layer touching your skin

Warm. Easy care. Lots of colors!

I use my thermal Smartwool as a sweater or base layer. I have 150 Smartwool in large that are slim fitting and great! But I got the heavier set and it's much larger and the pants are very big. Not so thrilled with the fit of my thermal weight - I I've the purple iris color! Its gorgeous. Just tr sizing is like an xl and that makes them too large. Very disappointing.
