During my trip to Iceland, I wore this as my base layer. So warm and cozy!

Bought a set for my boyfriend. He can’t stop raving about it. Super soft, keeps him warm this time of year as he works outdoors. He’s usually a medium in clothing but I purchased large as recommended in reviews. Fits perfectly. So definitely order 1 size up. I plan on getting him a couple more sets! Amazing quality for a great price. He prefers these over the expensive under armor thermals he’s had in the past. Two thumbs up!

Have you ever thought to yourself why is my lower half cold? Its because you haven't purchased this item! And if you have... you might be wearing it wrong. I would suggest putting them one leg at a time.

Got these as I needed a nice heavy duty thermal for my lengthy commute here in Denver in the Winter.

I bought this thermal fleece top for my husband. He really likes it because it is warm without being bulky.

These are not like thermals you are probably used to or picturing in your head. These are thin and feel like smooth felt. I don't own any clothing that feels like these do, very unique in that regard. It's still late summer here so I can't attest to how warm they are but one thing is for sure, they don't feel scratchy or uncomfortable. They are more like wearing silk. You may not even notice you're wearing them.

Very happy with this product! It is very warm and comfortable. The sizes are accurate as well. I’m normally a large and the large fits really well. Definitely recommend.

One of the best sleep shirts around, I know it is meant to wear under clothing for outdoors but wow, this shirt is great to sleep, keeps your arms nice and warm.

These are very lightweight and at first I doubted they would keep me warm. Once I wore them outside the first I was amazed at how well they kept me warm. They do run a bit small but not much, and they have a good stretch to them. Well worth the price.

Oh so toasty! Fit great and very warm. I sort of ordered by mistake thinking I was getting my old time Woolrich longies and was initially disapointed not to have cottom lined wool I have been using for over 50 years. However once trying on just for the heck of it they fit great and are actually warmer that the old wool stuff. My how technology has progressed faster than I. Mine did have a fly, unlike other reviewers that said no fly so maybe they listened to buyer feed back. I guess I am moving to the new high tech life now.

True to size and comfy. Layer it on top of layers. You can't go wrong!

Just what I'd hope for. Great fit. I ordered a size larger so I could get the length needed for shirt to stay tucked in. Very happy I did that.

After reading other reviews, I ordered a size larger than my normal XL and I'm so very glad that I did. I've never ordered anything 2XL in my life, but this fit perfectly. I've used these for downhill skiing and they are wonderful for that purpose!

This is a really warm thermal underwear set that fits snugly but stretches. It is very soft inside and feels like flannel. The outside is a breathable material like polyester that does well for sports or camping/hiking.

My wife and I recently moved to NY and decided to purchase thermal underwear before winter begins. We ordered 2 sets, one for me and one for her, that arrived as promised. The sets arrived packed nicely. They feel comfortable and very warm and the inside lining is very soft. Looks like good quality material, definitely very comfortable to wear and a must have for a cold winter. Great product for a good price!

These are the nicest thermal pants bottoms that I have ever purchased. They are very warm and comfortable and they are sized perfectly. The thermal pants elastic waist band material is very wide, which means they stay up well and they are very comfortable to the waist. If I had not bought as many as I did I would have re-ordered this product without a doubt. I will never wear my older narrow elastic long john bottoms ever again, they are going in the rag bag.

This fabric cannot feel any softer on my skin. You just want to sleep in it all day and night long. Mix and match your colors!

So far so good. I workout, so my legs/hips are a little bigger than average. Yet, the medium fit fine. If I got the large, I assume those would fit fine as well. I wear these under my jeans or pants on cold days and they do a good job of keeping me warm.
