Customer Reviews Smartwool Merino 250 Base Layer Bottoms

Awesome for pilots!! Got these for my husband who spends time on icy cold, windy tarmac's!! Not only does he love the pair I bought him, but wants a collection of them.

Nice quality.

Warmer than my last base layer. Soft material is nice to wear.

Perfect fit! 6'1" 200 lbs size L fits great. Hiking along the chilly Atlantic coast in Maine in January and these bottoms were ideal.

Great fit, wear it under different trousers while I'm active outdoors. Really comfortable.

It is perfect product for winter

Warm and very comfortable

Perfect. My legs were cold but now they are not. I still wear them with boxer shorts underneath just so I can extend the time between washes, but they are comfy on their own as well.

I wear this every morning when walking my dog, whether on its own or throwing on a light hoodie over, or a heavy jacket over depending how chilly it is and it is a lifesaver. Love how it fits and love how it feels. Itchy at first, but after few hours in a vinegar bath, massaging some conditioner, rinsing, and a couple cold water, air dry wash cycles, they are good to go and will be with me for a LONG TIME. For skiing/snowboarding or in the winter elements, this is a MUST.

feels very soft on my skin and great temperature control

I use the long underwear when hiking in the cold and they keep me warm. I use the short underwear for hiking in the heat and they perform very well. I sweat a lot, so I wash them a lot and they hold up well.

I wear these long-johns when the temperature drops below 35. They are warm, well made, and very comfortable. I love them.

Still pretty light and not overly warm. Helped keep me dry when I was sweating while snowboarding. Would purchase this again.

Good fit and very warm!

Warmest most comfortable pair thermals I've owned. I work outside during winter loading cars so I need something that's breathable, not bulky, pulls sweat away for I'm not getting cold. This superior feel, comfort & warmth. Worth price as ordered 2nd pair these warmest ones. See how they do. I now own 3 pairs, 2 lights, med.

My son uses these under his work jeans. He is picky & only likes the thermal wool brand. Keeps him warm & comfortable all day!

My boyfriend likes it!

Purchased for my husband and he loves them.

I have worn these a few times! I work outside and they keep me warm all day. The quality is very good too!

These Smartwool long Johns are my first line of defense against the cold in this New England winter!

This is an awesome product. I ended up using what I bought the day after I received it. It was all great and a good decision on thinking about it without complaining about it. I just wear it onto a good run and ended up going flexible, all throughout my experience in running in the cold.

Best product on the market if you are headed into cold weather.

I gave these as a gift to someone who does home remodeling and the spaces aren't often warm. He is excited to wear them and the color is great!
