MAXHEAT Mens Thermal Underwear Long Johns Set with Fleece Lined

Extremely warm and comfortable—perfect for my trip to Alaska. Note that it runs small, so I recommend ordering one size up for the best fit. High-quality material and well-made, keeps you cozy in freezing temperatures

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! 01-31-2002-23-20Returned 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!

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

Nice thermal layer. I’m 5’11 200 lbs and they are a little snug. XL fits well but might be meant for someone a little leaner than me.

These thermals are keeping me warm and comfortable, no matter what Winter throws my way. There is an inner material that is soft against the skin which makes the thermals also block wind. Have noticed zero problems with range of movement, almost like wearing a second skin. Am very happy with them.

Nice & warm, looks good. I dislike the feel of the material. Will not buy again , going to go back to old fashion good feeling longjohns.

For everyone concerned with the size let me clear it up. I am 5ft 8 185 and the large (m100) for me perfectly! These long underwear are meant and should fit very tightly, like a wet suit. They also create warmth by you moving around. Thats how they are designed. I wear them under a cross country racing suit on extremely cold -10 to -20f and after the first mile I am toasty warm. They may feel cold when you first go outside but that’s ok start moving! They are also NOT designed for a “dad bod” . So if that’s your body type I would suggest a thicker and looser long underwear. If you are a x-ski racer, alpine racer, winter runner, fat biker or winter hiker I would highly recommend these long underwear. I live in MN where winter temps can be brutal and these are my go to base layer every time.

I bought both the top and bottom and I love it.Specifically I like that it fits tightly and comfortably (better then other thermal underware I bought ~10 years ago), I like the soft internal layer and the different feel for the external layer, I like the design (the stripes) that allowed me to put a t-shirt on top of the top and wear it to semi-public spaces - it did not feel like an underwear, and the most important - I provided me the thermal insulation: I used it on my sail passage from Seattle to San Francisco in September (it was quite cold up there in the ocean this September), and I am looking forward to wear the set during my skiing trips, so I definitely recommend (and already did) the product, and the only wish I have is that they make this product for kids.
