Why We Like The Smartwool Classic Thermal Merino Baselayer Bottom

If the forecast says things are getting cold, then we're throwing on the Smartwool Classic Thermal Merino Baselayer Bottom. As Smartwool's heaviest knit, this baselayer provides us the soft comfort we love and the breathable warmth we need while making our way to any summit. Even after the hardest outings, merino wool wicks away moisture and helps reduce foul odors so we're always feeling fresh.

Merino wool leggings

I've used it once or twice and have initial impressions

Large

Not what I expected. They got baggy and loose right away. Not form fitting at all. I would not order them again.

I've used it several times

I wore these for a couple runs when our temps dropped under 20. Very comfortable and wind resistant.

Seems didn't last. Super warm and worn a few times while adventuring with littles but the seems in multiple spots came unraveled.

I’m a dude, and it looks great on me

I want pink, but they didn’t have that in men’s. I’m 5’8, 165 pounds, and I bought an XL, which is a little bit baggy so I would probably get a large next time.

Super warm thermal leggings!

Familiarity:
I've used it once or twice and have initial impressions
Size Bought:
Medium

Bought these to have for when it is cold and to keep me warm when camping during winter. I did a lot of research before I purchased these. They are pricey, but worth it. First of all they are thicker and the fit is perfect. They are also flattering and not so thin which allows me to wear them as normal winter leggings as well. Also as pjs around the house during winter too. I loved them so much I decided to buy two more pairs and the base layer tops to match. If you are able to afford these and want thermal base layers that last then these I highly recommend. I’m 5’6, weigh 133 lbs, 30 inch lower waist and a medium fits me perfect.

They are high waisted and true to fit. I'm a curvy woman and they fit very comfortably. I wore these under my jeans in Japan in January. They kept me warm and they are oder repellent which is nice while traveling. Highly recommend.

I usually struggle to find the perfect fit in bottom base layers, but I was pleasantly surprised to find these fit like a glove right out of the box. I have a bigger bum and run into the issue of layers either being too snug at the waist or too loose at the thighs, but I did not run into this issue at all with these. I wear them casually after a day on the slopes as well and can absolutely see myself wearing them camping, hiking, and in just about any outdoor scenario where the temps drop!

Low rise

The fabric is nice. Unfortunately these are low rise and definitely made for someone with a flat butt. Nice and long though which is what I like. Couldn't keep them though due to that low rise.

I purchased new merino wool layer for a river trip in February. I loved them. Just an added layer to my fleece layer but they were Perfect. Can wait until they are the only layer under my drysuit.

My favorite baselayer!

I love my Smartwool Classic Thermal Merino base layers! They are soft, super warm (especially given their thickness), retain their shape, and don't get stinky, even after multiple wears between washes. I wear them downhill skiing, touring, and under my street clothes at night. I normally wear an XS, but I sized up in both the bottom and top.
