Customer Reviews Smartwool Classic All-Season Merino Base Layer Bottoms

Super comfortable and warm. I have been using the all weather bottoms and two different weights of the 1/4 zip tops for years now and have no complaints.

Used for cycling and all around wear. Fit, finish and comfort are superlative. I'll be ordering a couple more for all seasons.

These are great baselayers, lightweight, I use them more to control sweating than warmth, better than any synthetic I've ever tried.

I use these when the temps start warming up in the spring and they are awesome. Seriously, where have they been all my life??

These bottoms are the perfect layer. I wear them most days in the winter for that extra warm and cozy feel. I work outside alot in the winter going to different building construction sites. When I have these on, I'm warm no matter how cold it is.

Once I start wearing long underwear, I end up sticking with it until Spring....sometimes that bugs me but this time, it caused me to buy 4 new pairs. I love the Smartwool long underwear because it keeps its shape wash after wash after wash and (based on some I've had for several seasons) I expect these to last. The fit is great and the shape holds up. More expensive than cheap cotton ones you can find anywhere but these are worth it.

Used the product as under base while attending outdoor sporting event in Chicago during November. Perfectly comfortable.

I walk a lot for work as a wildland firefighter and these are a great base layer for fall and spring work. Breath well and strike a good balance of warmth without overheating.

Great shoulder season layer before the winter really sets in and you need the heavy weight layers.

I wanted a wool based product for a back country hunt trip and need to pack light. This is a great product for day and night wearing. Good quality and comfort

If you have an issue with a rash when you wear polyester long johns just try these. Amazing feel and no rash.

Perfect weight.

I have been wearing 'performance' base layers for years. I have not been impressed...until this. Boundary Waters canoe trip in May. I slept in my base layer, got out of my hammock, paddled and fished all day. Total comfort!

Great! So comfy!

I order these for my husband who owns a food truck and is outside, in the mountains, everyday. He LOVES them under his Chef pants.

Great base layer for casual cool weather activity. Has a comfortable waistband and appropriate leg length.

I only use Smartwool base layers. They are the best

Always the BEST in base layers and socks (and everything else!)

Bought these to replace some polyester bottoms I've had for a while...these are softer and much more comfortable. I expect have them for years. I'm 5-10 and weigh 165...great fit.

These base layer bottoms are my go-to for cold day runs here in Maine (sub 15F). They are totally comfortable and keep my legs warm underneath my running tights. I also put em on at night at home: nothing better to lay around in on these long winter nights.

I haven't worn them for activity yet, but they feel great when I try them on. I feel like they'll make a great addition to my camping gear. Thank you!

Just wore them for the first time in 20 degree weather downhill and backcountry skiing in New Hampshire and they are fantastic! Warm, breathable, and comfy!

All time favorite layering piece for cold weather.

Excellent comfort and warmth!

I was very pleased with how well they fit. I'm now thinking about buying more when I get enough to pay for them. Thank you so much!
