Great Base Layer But Sized Up For More Butt Room
Smartwool makes fantastic wool items but I had to size up so that where was plenty of height from the crotch to the waistband. My normal size didn’t come high enough up on my waist and I would have had to hike them up every time I had to squat or bend over. Just a hair too short in that area. Otherwise a great product.

Smart Wool Base Layer Works Great.
I’m in Colorado these are nice under pants while at work. I’m 57 130lbs I ordered small . They fit fine. I have cwx insulated compression tights I would normally wear but I opted for these because they are less restrictive for wearing all day and even multiple days in a row .

Comfy
Bought for my step son. He loves them for the comfort and extra layer of warmth out in the Minnesota winter weather. Now my daughters all want some!

Cozy
Great fit and easy to layer under work pants. I was looking for a lightweight base layer to wear all day and these are perfect. I'm buying 2 more pair.

Snuggle'fest For Your Loins
Look.... I'm sure there are other layering products out there that get'er dun, but SmartWool has always been my go-to and has yet to disappoint. We all would rather have soft smooth wool rubbing against our thighs, rather than the cold evil touch of your winter pants. Your delicate tid-bits are also grateful. Do yourself a favor, get some smart wool and create your own snuggle'fest down yonder in the nether'regions.

Light And Warm
This is warm for its weight and thickness. it does its job. feels good on the skin, non abrasive. it is thin though, and with that thinness comes the see through effect, i wear it under pants or shorts so im not advertising too heavily!

Good Long Underwear Bottoms
I've bought these a few times before, and this one didn't actually arrive, but it is a good lightweight long underwear. This is lightweight merino wool, so it isn't super durable, but it is good for what it is.

Simply The Best!
I purchased some Smartwool base layers about a year ago and REALLY like them. I bought the 250's first and they are terrific. I then purchased 150's (tops and bottoms) and got rid of all my other brands and am a Smartwool guy only. They are soft, wear extremely well and wick perspiration better than any other brand. The big bonus is NO SMELL after wearing them for extended periods of time on back country hiking and hunting trips.

Great Base Layer!
I have had these merino bottoms for about a month now, and been very impressed by the quality and feel of the material. This was my first time trying merino clothing - I’ll definitely be getting more in the future.

Comfortable
I bought these to replace a worn out pair. They breathe better than synthetic and don’t retain odor if on weeklong trips. The fit is as expected

Nice Base Layer
Used these a few times now. The fit is typical base layer tight to skin. They fit nicely under normal clothing and work well as sleeping layer in the sleeping bag. Adds a nice thin extra layer for warmth.

Great Material! Excellent Fit
Bought this for working in the forest and hunting. Great for staying warm in cool mornings while breathing well as the temperature increased through the day. The material is nice against the skin, and the fit was as good as I could hope for.

Perfecto
I got these thermals for an elk hunting trip to Colorado. I use them as sleeping clothes because it’s cold at night but warm in the day in September. I had used Kuhl thermals before but much prefer these from Smartwool.

Feels Great
I bought this pre-season, and it has become my go-to baselayer for skiing. Fits great. Feels great on my skin. I'll buy more in the future. .

Can’t Beat Wool
These are exactly as advertised. Warm, dry and and don’t smell after multiple days on the trail. My wife thought hers felt scratchy but Mine are comfortable.
