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

Great light weight, soft merino wool! Great for layering while on the trail!

Used it this past weekend in subzero weather snowmobiling and washed ready for downhill skiing. Warm as base layer. Washed beautifully! Feels great against skin!

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 enjoy the added layer this tips gives me on cold days. It's a great layering piece or nice to wear on its own.

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.

Wear this to keep warm but comfortable this winter. Love how soft and comfy it is.

I usenit for all outdoor activities with a javket or sweatshirt based on the weather.

This is the fifth merino base layer crew I have bought, in all different colors - the first one is at least 8 years old and looks exactly the same as the day I bought it. In the winter months I wear them almost every day and wash each one at least once a week. I absolutely love them. The perfect base layer.

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 use these tops for workouts, hiking and walking, or simply around town. They are my wardrobe workhorses. When they get damaged by my use, I use them as PJs.

Great layer for all my winter sports. This layer is perfect for a warmer winter day where I need light layering!

I wear this under a wool sweater. It is soft and does not stink after one wearing.

I use this as a warm layer with a soft shell on cold morning runs (20 degrees F)It wicks well. The fit is fitted but modest enough that I would wear alone. It holds shape thru the wash and dries quickly. No funky sweat smells!

I purchased both 150 & 250. The heavier for skiing and lighter for figure skating. Perfect!

Great everyday winter basic. Versatile piece.

Runs a little small- usually mediums are baggy. Love the orange sherbet color.

!Smartwool always delivers. I trust their all-season shirts and know the fur, durability and warmth. Their wool is not ever scratchy and always provides an enjoyable wearing experience. Although a con is the cost I watch for sales and know their quality is worth it. They're my go to in all seasons except the hottest Arizona summertime. Thank you Smartwool!.

this was a present for my daughter and as she just received it, she was very excited at how beautiful the color is, how soft and great it looks. Will wear as a base layer.

I wear this as a go-to too. I can wear multiple times before needing to wash. It is very soft and comfortable, fits great too.

I bought these shirts indoors specifically to use for cold weather. With heating costs rising I expect to to be able to where these shirts and stay warm even with the heat lowered.

I'm always cold in the winter indoors and out. NY winters mean turn the heat up or wear something to keep warm. I've always gone to merino wool for warmth without bulk and expect these shirts will do that. This is my first time buying Smartwool tops, but I've been buying their socks for years. I was hesitant to spend the money, they are not inexpensive, but if the shirts work as well as the socks, I will be very happy.

I love the fact that the wool has some stretch in it and that it is machine washable. I can where it under something else or on its own. It's a staple for me for travel (lightweight) and for cooler weather.

I love this brand. The everyday warmth that works well for me in winter also. I feel the size mint is accurate and flattering. My only negative is the lack of colors. Wish there we more green (medium to dark) and more blues (royal blue and/or navy). Otherwise this is my go to shirt for year round wear.

The underwear is very light and warm. I always take it with me on winter trips I sent it to my friends in Ukraine so they can stay warm.

Purchased for upcoming European Christmas Market trip. Will be a perfect base layer
