Very warm & comfortable. Not bulky, ordered another 2 pk

I was looking for something to wear underneath my cloth, not too thick or heavy and these are perfect

Warm but lightweight base layer. The thumb holes are nice and they are sewn well so they won’t tear over time.

These tops are soft. After reading some reviews I didn’t expect them to be so comfortable. Would recommend.

Very comfortable and functional upper and lower thermal underwear. Not bulky under clothing to restrict moving about.

Bought both XL & XXL, but can't really tell a difference in sizing, so sizing is... subjective. :) Got them for a great price though, so keeping both sizes.

For reference I am 5'7", 110 pounds, 32C, 26" waist. I purchased this in a size Small. It was a perfect fit. Not boxy nor tight, especially around the waist. I have a long torso and although this shirt didn't cover my bottom, it was long enough for me. I have long arms and the long sleeves fell at my wrists. It's lightly lined on the inside and kept me warm during my walks outside in 50 degree F. I wish it came with more colors than black and white. I highly recommend this product.

A tad thin

Fabrication has changed.. I'm very disappointed. I've bought these tops and bottoms for several years now and have them a LOT in the winter. They are less stretchy now and the tops shorter. I bought XXL this year and they feel smaller than the XL's I have from past years.

These are amazing! I'm about to go on a month long winter camping and road trip and I can't believe how amazing these are. They are super soft and flexible. They are even more soft on the inside. Just went back and bought two more of each for my trip. I got the bottoms too. Sizing is accurate. Fits like a glove. Just like thermals should, without feeling too tight or restrictive. They couldn't be better. I was honestly really skeptical when I first opened them up and saw them, but they are so amazing. This might be my favorite thing I've bought for my trip so far. Super comfy! I almost never go back to buy more clothes of the same thing, but this time I made an exception. These would be great if you work outside too. I can think of a lot of practical applications. I think it would make great lounge wear too.
