Warm, Soft, and Comfortable Base Layer
This thermal set is very warm and comfortable. The fleece lining feels soft and keeps heat in without feeling bulky. Fit is good and it stretches nicely, making it perfect for layering under jeans or winter clothes. Great for cold-weather walks, workdays, or outdoor activities.

Soft and seem pretty warm
I purchased the small and medium and kept the mediums. I’m 5’6 and 120lbs and they are slightly baggy, but still tight enough to wear underneath jeans and work scrubs, which is what I need them for. The material is soft and comfortable, I’ve only worn them once and am pleased so far. We’ll see how they hold up.

Slim, comfy and does the job for 30-40 degree weather
Bought for my first trip to cold. It did so well, I could use just the shirt without a sweater and it still kept me warm. It was very comfortable, fit very well, lightweight for packing, and sleek looking for style. No fleece but it did its job.

Best For Moderate Cold, Not Bulky.
This thermal underwear is good as a base layer if you’ll be out in temps in the mid to upper 20’s or above, but it’s not great for extreme cold. It is made of thin material that works well for sliding jeans over due to its lack of bulk. I will continue to use my several sets of Cuddl Duds for the really intense cold while this underwear gets utilized for the more moderate cold. Fit was as expected and it is comfortable with plenty of stretch.

Soft, warm not bulky
I am very happy with these! The underwear is warm and lightweight. I don't feel like a stuffed sausage with them under my clothes. The sizing chart is spot on and they fit really well. I would highly recommend for anyone who needs an extra layer of warmth for the winter

High quality, multifunctional. Keeps warm and very comfortable.
My experience with thermal underwear is fairly limited, and there are too many options on Amazon, but I can safely say that these fit the bill. They were shockingly comfortable, like PJ lvl comfortable, and I didn't have any issues with rolling or shifting around (i'm a 5'4" shapely female). I believe I even wore the bottoms on their own at once point, I have no concerns with it being see through. They kept me plenty warm and may become my new house clothes.

Very Comfy and Sturdy
I love this thermal underwear! I purchased a silk pair, and although they were extremely comfy, they snagged very easily. The same with another brand, which pilled almost overnight just from the friction of wearing them. This set is sturdy, and I don't have to be so gentle with them. I can throw them in the washer on gentle and dry on low. They are excellent for layering or wearing to bed in cold weather, and not too heavy . I am very pleased and have just ordered another set.

Would not buy again
Shirt is warm and liked. The bottoms are too loose and ride up under pants and just not warm enough.
