Review: Worth the money! - Arrived on time. Fits great and feels so comfortable. You can wear it for pajamas if you want. Good quality. I would recommend this product to a friend.
Review: Comfy and Warm - Fit Well - Got these for an upcoming ski trip and immediately tried them on when they arrived. I am getting another pair now. Im 5"10, 170lbs, so pretty average size. Medium fits me perfectly. They are bit snug (which i want for a base layer) and very comfortable. The neck/collar is a little big, but no different than some of the v-neck style shirts today. The exterior has a spandex/lyra feel while the inside has a microfeecy kind of feel. They feel a bit thicker than a regular base layer and seem to be pretty warm. Will write an update after my ski trip and getting to use them in the wild, but I am pretty impressed thus far! 01-31-20 02-23-20 Returned from my ski trip. These are great! I got a 2nd pair after my previous post. These are warm and comfy and layer well. It was -11 for several days and I was fine with these and thin/waterproof shell pants on my bottom half. For my top half, I layered with a light performance jersey and light wind breaker with an outer shell. I never felt cold. I wore these as my base layer for 2 days of active skiing and they didnt stink after removal. No issues with stitching or quality thus far and i have washed them now a few times. These seem like a great base layer for a wide range of winter temps!

### ⭐⭐⭐⭐ Sizing difference makes a real good set worse
*by I***N on January 30, 2019*

I am a 6'1 220 lb guy and i ordered a Large based on the waist measurements. The bottom of the set is wonderful! The material is stretchy and soft and it seems to keep heat pretty well, but when in a warm environment it doesnt run too hot. They also fit really well.I would def get a Large bottom of this set again. My issue is the top. The neckline is weird, it seems to go down my back more than i would like. I am fine with how low it is but it seems cut weird. The sleeves are really small too. They ride up on my arms a lot. The chest is pretty tight and the shoulders are real tight. The material is soft and comfortable though, and i could see myself wearing it if the fit works. I will try to order the set seperately next time. and getting a Tesla also to compare
