Bought these to use as an alternative to fleece lined work pants. Much prefer these as it provides more flexibility, yet keeps you warm. They fit well and pair with my canvas work pants. I particularly like the idea that if the weather warms up enough, I can simply take them off, whereas with lined pants, you 're stuck unless you keep an additional pair of pants with you. These launder well too. The seams in them are placed well so there's no `` tugging '' or tightness. To me, they 're a great cold weather investment.

I received this set of base layer pants for a Carhartt Crew Filed Test to test its warmth, comfort, and durability in real world working conditions. This is by far the warmest and most comfortable set of base layer pants I have ever worn. I wore them over the winter in Colorado and Wyoming in cold weather, heavy snow, and strong winds. I was warm and comfortable no matter what Mother Nature threw at me. They wick away moisture and move with me all day. I would recommend this base layer for anyone who works outdoors in the winter.

Received these thermal pants for Carhartt field testing. They strike a nice balance between being very warm, lightweight, and comfortable. Wore under double- front jeans or canvas pants in single- digit temperatures with negative wind chills and my legs stayed warm while moving/working. Their light weight is nice for putting in a pack if it gets too warm while hunting or hiking. They are also comfortable to lounge in in warmer temperatures! Pants are true to size and seem durable, however, I have heard thread stretching when I put them on from time to time( I wear size large and am between a 34- 36 waist).

I am impressed with my Carhartt Poly- wool bottom. I received the thermal as part of a Carhartt Crew Field Test, but I will be ordering two more complete sets. I am truly amazed at how well this bottom works to keep me warm. One must understand, I am constantly cold, so to me, this is amazing. I am 5ft 3in, and weigh 115lbs, and the small works well for me. I have laundered it, with no ill effects. It has retained it's shape and fit very well. The bottom also fits perfectly under skinny jeans, without bunching or showing. I live in Iowa, and it gets cold here. While wearing this pair of thermal bottoms, I stayed warm. It really goes long way in cutting the harsh winds we get out here on the prairie. I can honestly recommend this thermal bottom to anyone who gets cold in the winter.

[ These are a really cozy and warm bottom layer for Winter. They run warm, so on a cold day, they are perfect. The waistline band can become bunched from wear and washing so you may need to reposition it after a few washings. Otherwise, a fabulous warm bottom layer that has a soft wool fabric.

I received the Base Force Midweight Tech Crew Thermals as part of a Carhartt Crew field test and I'am so happy I did because I love these thermals! My favorite part is the thumb loopholes that keeps your thermal shirt in place when you layer over top of it with jackets or sweatshirts. The thermal is very comfortable and kept me dry at all times. It has sweat wicking& prevents odor. You can not go wrong with this thermal and I highly recommend it.

MELANIEW
I couldn ’ t be happier about being chosen to field test this set! As requested I wore these as much as possible( 3- 4 x a week)! These are honestly the best thermals I ’ ve ever worn!! Whom ever designed these thought of everything!! From the warm ultra soft moisture wicking fabric that keeps you dry and toasty, to the stay in place thumb holes in the top for comfort, you couldn ’ t ask for better thermals!!

Love the deep purple, top base layer! It fit really well and was long enough despite my 5' 11 '' height. If you are a C cup or bigger, you might want to size up, but for anything smaller it should work. It's odd that this was long enough but the matching pants are not as I 'm very proportional. In any event, I 'm grateful to have this top and I love the feminine color! Thank you!

Cold weather underwear is typically made from materials designed to provide warmth and moisture management. Common fabrics include merino wool, synthetic blends, and thermal knits, which help retain heat while wicking away sweat. These materials ensure comfort and insulation during colder temperatures.
When selecting cold weather underwear, consider features such as moisture-wicking properties, thermal insulation, and a snug fit to trap warmth. Look for options with flat seams to reduce chafing and those that offer breathability for comfort during physical activities. Additionally, some styles may include added stretch for better mobility.
The fit of cold weather underwear is crucial for optimal performance, as a snug fit helps to trap body heat while allowing for freedom of movement. A well-fitted base layer should not be too tight or too loose, as this can affect insulation and moisture management. Proper fit ensures that the underwear stays in place during activities, enhancing overall comfort.
Yes, cold weather underwear comes in various styles tailored to different activities. For instance, some designs prioritize warmth and insulation for low-intensity activities, while others focus on breathability and moisture management for high-intensity sports. Choosing the right style based on your activity level can significantly enhance comfort and performance in cold conditions.
Cold weather underwear is primarily designed to be worn as a base layer, but some styles can be versatile enough to be worn as outer layers in casual settings. However, it's important to consider the fabric and design, as some materials may not be as durable or stylish for outerwear. Layering with appropriate outer garments is usually recommended for optimal warmth and protection.
