Customer Reviews Smartwool Merino 250 Base Layer Bottoms

The perfect combination with a pair of lined utility pants. Some might say that it doesn't get that cold in Phoenix MD, but this fall the has been fiercely winty and this layer has been great for that.

As a car salesman, most of my free time is spent standing outside for up to hours on end waiting for a customer to roll in. These base layers keep me warm while motionless in the upper Midwestern winter, they have made my workday much more bearable and comfortable.

Super warm and very comfortable

Best base layer out there! Super comfortable, can wear for days on end.

I wear my smart wool under my clothes every day in the winter helps keep my temperature regulated. Once I get cold I cant get my body back up to a comfortable temperature unless I take a hot shower and I cant do that in the middle of a work shift.

Works great for a base layer out on the cold river. The size S is a nice close fit for me at 5'7", 145lbs. Love the feel of wool.

My wife and I are climbing Mt. Kilimanjaro in late June and this purchase completes my hiking gear for the hike. I wear my 4 x 1/4 zip 150 & 250 weight tops all the time and recommend Smartwool to any one and everyone.

I purchased this for my base layer. I do wear 3/4 pants but wanted an added layer on cold days. I like the product but my one complaint (or suggestion) is to offer a 3/4 or short/ tall versions. I'm a short 5'10" and a medium was too long. I originally purchased a large and they were swimming in me.

Great base layer! Very warm and doesn't restrict movement! Highly recommend for anyone outside for hours during winter. Use them during winter days for delivering packages.

Quality is good as usual for Smartwool. Shipping leaves a lot to be desired. It was supposed to be delivered 2/7 finally got it 2/14. Tracking wouldn't open at least half the time. Never on computer only on phone. Will look hard to buy some place else

Not as warm as i thought

Great layer when it's cold. I work outside and these are great when it's winter time. Fit right and always keep me warm.

Long time buyer of smartwool. These were a bit lower cut at the waist than my old pair, so I like the fit of my old ones better. These are excellent for what I do (backcountry skiing). I wear a 34 waist pant and bought a size large. The website would not let me select a star rating.

Love the Smartwool Cassic Base Layer. It is very comfortable. They are very pricy and it was more than I wanted to spend but I am happy. I have a long inseam so really my only grip is that I would like the length of them to be a bit longer to reach my ankles.

I have a lot of synthetic long John's, but these wool ones are far superior. They just keep you warmer.

Perfect! Works great tucked into socks and work boots over top.

These are a huge upgrade from my previous non-merino wool base layers. I wanted to get away from the plastic fibers and these were better than I expected. The Medium sized fit my 32inch inseam perfect and the feel is so much better than my previous base layers!

Love the weight and warmth. I will keep supporting Smartwool.

Unfortunately I decided to return this item for the very reason the waistband was uncomfortable. I had owned an old version of these by Smartwool that I was replacing. The older model (many years old) had the waistband that was much less constricting and was covered by material. It was very comfortable and you hardly knew you had them on. This new version is also 100% merino but the waistband is not covered and is pure elastic. I found it quite uncomfortable and I always knew I had them on.

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

Can't live in the winter without these. Bought these so my husband would have enough pairs to get him through each week, as he works outside in the cold. We Love them so much. I wish that Smartwool would make a small design adjustment and put the "hanging tag" on the outside! - Not the inside where it is very irritating on the small of your back. Other than that, 5 stars on these!

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!

Just the right weight of fabric and the wide elastic waist band works well. Second pair. It's an investment.
