Customer Reviews Smartwool Intraknit Thermal Merino Base Layer Bottoms

A great product that keeps comfortably warm without all the bulkiness or sweaty. I use it to ski and can ski all day without having to peel off other layers of clothing.

I use this base layer for work and hiking, and wow, it's kept me warm in this cold winter days. We constantly stay outside for work, and I'm at my most comfortable

Long lasting great products

Great product!!! I'm a firefighter and we go to extreme cold quickly with most calls we run on. The Thermal Merino base bottoms keep my legs warm which I turn helps my back still function. :-) These are my third pair love them and wear them most days of the winter! Thank again to smart wool! I love a company that stands behind their products!

Great base layer! I have worn them at -10 degrees with just one layer above and was warm. They are soft and comfortable to wear in any situation.

I use this product for long walks on very cold days along with being outside during cold weather sporting events. Like the fact that that it is snug fitting to keep cold air from coming under the garment. No real complaints except some type of fly would be nice along with some other colors, especially navy.

I use the product while skiing - love it

Excellent running T during cold temps.

Has kept me warm during full days of skiing. It's usually the only thing I wear under my parka.

Outdoors fat biking. Great base layer. Trail running in cold weather.

Biking

Use these primarily for skiing. Very comfortable and warm. Even in below freezing temperatures, with a shell on top. Also quite breathable when I exert myself on a hike uphill, get worked up on difficult terrain or when the forecast is wrong. Very satisfied with the fit and the way they move with me. I may buy another pair and would certainly recommend them. Remember not to put 'em in the dryer !

Comfortable and cozy! Wore it in extreme cold weather and it allowed me to go extra mile.

Absolutely love these! Already bought a 2nd pair!

Great base layer very comfy

Use as base layer for alpine skiing. Excellent performance.

Loving my Smartwool base layers

Used while working outdoors in coastal Massachusetts in 35F and below weather. Significant winds/windshield, snow, rain 45 hours per week no matter the weather. This protects your core from the frigid winds as a great base layer. 10 out of 10 stars would buy again.

This is used in 35 F and below on Cape Cod during the winter, 5 days a week while working outside building new homes. The wind chill often creates frigid, miserable conditions for 8 hours a day so a warm, comfortable base layer is necessary. The mens Intraknit is light, made of comfortable fabric but keeps the body warm in sub par conditions all day. The only draw back is it is missing a fly opening, which makes using the bathroom in an ice cold port-o-john a little less awful. A little. Regardless, 10 out of 10 stars, would buy again.

Use them for biking, hiking, skiing. Any the big outdoors when it gets cold

True to size and perfect under my hunting pants

very comfortable

Comfortable and fit great!

These are great to wear all winter. They keep you nice and warm when it's freezing, but also not too warm when the weather is warmer in the winter. You can wear them around the house with just a t-shirt underneath or under your outdoor gear.

I work outside everyday in all types of weather and these have out performed everything else that I've tried. They are very comfortable and durable. As far as I'm concerned this is the only base layer that I will own.
