Customer Reviews Smartwool Classic All-Season Merino Base Layer Bottoms

All day wear

These pants are a game changer. I'm out in the cold a lot for work, and nothing has been keeping me warmuntil these! They're thin enough to wear under other pants, and they keep me so warm. I absolutely love them!

So comfortable and felt great in the freezing cold.

Great product. Warm, comfy, quick drying. I will buy Smartwool base layers forever

Live in Michigan so weather is cold in winter, work outside and inside so I needed a base layer that was warm enough and at same time wouldn't overheat when indoors ! Great product soft and fits perfectly.

This base layer is great for being out in the field doing trail work especially during cold and wet days. The bottoms are comfortable and give me just right amount of warmth without restricting movement.

Easily my most used base layer from Smartwool. During my guide season, they are perfect in fishing waders-warm, comfortable and durable. In the winter, they are under ski pants, lightweights when snowshoeing, and under regular pants when shovelling snow! Couldn't live without them!!

Use it for biking, hiking, skiing and all times in the cold

Great ski base layer.

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

Good base layer to keep my lower half warm.

Repeat purchase because my son loves these for working outside.

Five stars these long underwear are amazing

Great quality gloves - gave as a gift - my son is going to love them! Just as described - definitely recommend! Shipped quickly!

The gold standard of base layers. Last forever and always do their job. Warm and dry, what else do you need on a cold day?

Purchased these as a replacement pair for my husband. He's had his last pair for 6 years! They are still wearable with only a few small holes at the seams, but new SmartWool is always appreciated. They keep him warm while backpacking and snowboarding!

Snowboarding base layer!

Great Temperature Regulation. Love Merino wool because it is soft and comfortable, feels lightweight and provides excellent insulation. It is moisture-wicking, reduces chafing and is naturally odor-resistant, so need for frequent washing. It is breathable and lightweight providing breathability and doesn't feel bulky under additional layers. High-quality Merino wool is both durable and resilient. Great for layering under clothes as standalone loungewear. comfortable, functional base layers. Best of all it is easy care and quick-drying.

Been looking for a new base layer bottom since my old PolarTec brand were over 20 years old. This pair has been awesome I went a size larger just in case and I do like that.

Perfectly balanced love it thanks

I have a pair of joggers that I absolutely love but I needed something for under my pants and to wear at camp at the end of bikepacking days in cooler weather. Just used these this past weekend. Warm and comfortable.

This is my second set of these base layers. The first set has lasted more than 10 years.

Great fit and comfortable without being scratchy!

These wool bottoms check all the boxes for me! They are a perfect mid-weight, so I wear them almost daily in the winter (have another color as well). They are warm, soft, not itchy, long enough for my long legs, ride below my naval and stay put with. Oh, and they're super durable. Five stars for sure!
