• Mens thermal underwear is a lightweight thermal set of both a thermal top and bottom made of a poly-spandex material that will wick away moisture to keep you dry with no sticky or clammy feeling so you can wear them all day.
  • Made of premium fabric, thermals for men have smart odor control to prevent the spread of smells as well as absorbing odor-causing enzymes so they won’t stick to your skin. You can remain confident that wearing these all day won’t cause any problems.
  • Built with flexibility, the thermal underwear is highly stretchable to offer full mobility. The fabric won’t hinder your movements so you can move freely while at the gym, office, or home. They are perfect for all activities and will keep you comfortable.
  • Men thermal underwear set is soft against the skin, yet its strong seams won’t rip or tear prematurely, offering long life. They fit snug like a second skin for perfect heat retention minimizing heat loss for an ideal base layer or worn on their own.
  • For even more added comfort, long johns for men thermal have no tags, which reduces any skin irritation. You can slip them on and off easily and can be worn under your clothes for added insulation and at the gym for added support and movement.

I bought a medium pair these long johns for the coming Winters, due to lack of long sleeve and properly close-fitting clothing, to replace bulky sweatpants and unsightly jackets, and also because for half the year my house is around 60 degrees. I wanted the easiest possible solution. Instead of overcompensating by warming up with hot showers, running around, double jackets, triple T-shirts, winter caps, neck warmers, sweatpants, triple socks, and/or even gloves, now I can just throw on these Thermajohns over my briefs, and with only the addition of socks and periodically a winter cap, I can remain terribly snug all day long in my home. Bring it on, Winter power outages! These long johns are thin enough, very comfy, and close fitting around the wrists, ankles and waist. Wearing them under daily clothes during Winter is very practical and does not change the natural shape/thickness appearance of your body. The arms are just long enough to not need rolling back for most things. The torso is just short enough that you don't need to tuck it in. The material is somewhat silky on the outside and like very soft wool on the inside. The fly is also easy to open, and the crotch does not restrict the forward space for your junk, allowing more comfort and sex appeal (it lets you protrude). At 170 lbs of muscle, it lightly hugs my legs and chest, a nice bonus as one can wear close-fitting clothing over it. Not much is more annoying than baggy or thick undergarments. I bought 2 pairs of these, would recommend them to anyone, and will likely buy more in the near future.

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.

Perfect fit (I got medium, and I am 5' 10" 175 lbs). Also, awesomely warm for upstate NY! Very soft, smooth material, not itchy at all. I have worn them under regular clothes and under my bike clothes and they are great either way.

I was going to upload a photo but my wife didn't want it on amazon so you'll have to take my word on it I am NOT a bodybuilder. I am a big 6'3'' 295 lbs hamburger eating, biker looking, lumberjack of a man and these fit snug at 2XXX... I do like the feel and they make my big fat round belly feel like a balloon yes that smooth round feeling. I got the white and my wife says I looked like santa aaaaw the romance is dead LOL no no but these do feel night so 5 stars but I should have tried 2XXXX is they had it because i am not a fan of tight.. :-) Yet I'm not a fan of losing weight so with that said These stretched great, feel soft, and neckline a bit small but then again I am big big big lol I bought the white ones...

My husband is from Costa Rica and this is his first winder in the cold north. He started feeling chilly, so we looked at Walmart for long johns, but they were not soft and they were about $15 for either pants or the shirt. This is the second set I have ordered in a week because he wears them every day. They are super warm and soft on the inside and thin enough to fit under your shirt comfortably. The fit is great, he is a big and tall guy 6'6''+ and 290 lbs so they are perfect. Some people say they are not the best quality stitching, but really the fit and fabric makes up for that.

This very well may be the best money I’ve ever spent in my entire life!! When I read that this item was fleece-lined I thought to myself, “Gee, that should feel pretty cozy!” I was supremely underestimating the comfort level!!! This product ROCKS!!! Not only did it feel like slipping into a second skin... it just so happens that the second skin is softer and warmer than my original skin!! No wonder animals are fur lined!! I will be ordering more of these!! I rode my bike with just a hoodie and sweatpants over these with the temperature around 42 degrees!! I felt like I was wrapped up and laying in front of a fireplace! Everywhere the thermal covered my skin, even while riding pretty fast... all I could tell, is that there was some wind.... didn’t feel the temps seeping through! If you’re athletic Or outdoorsy or working outside... BUY THIS NOW!! And when the temps get even cooler... I’ll just slip on two pair!!! I will never purchase any other thermals!!! CUSTOMER for LIFE!!!

I bought these thermals for my husband for a winter trip to Utah. As advised by other reviews, I sized up to Large. The idea of my medium-sized husband wearing these has me giggling. Maybe he could squeeze into the shirt, which fits like a men's small, and considering they are meant to be worn as an under layer, I can forgive that. But the pants fit like women's small/medium. That said, I am 5'6 and 125 pounds (usually a small, sometimes a medium) and the men's large set fits me great! It is so comfortable!! I wear them as warm jammies or just the pants as warm leggings out and about. I am considering buying another set. Apparently there are two types- the kind we received doesn't have a fly on the pants.

They were a perfect fit. I'm 5'6" and 132 lbs with a 28 inch waist. I ordered a small. They are incredibly soft and I didn't want to take them off after trying them on. I have broad shoulders and found the sleeve length could be a tad longer. I'm used to wearing another brand that has the thumb holds. I could probably get away with wearing these in a yoga class. I wore the top to work on a casual day and you no one would know it's a thermal undershirt.

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 usuallly 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!

Although the size charts indicated that an XL was ideal for me, I was initially persuaded by several other reviewers to order a few sizes up so I went with a 3XL. This turned out to be a misguided decision. While the top and bottoms were still somewhat form fitting, it was apparent that they were significantly oversized so I returned the 3XL and ordered an XL instead. The XL is a much better fit, especially since this is intended to be a base layer. For what it's worth, I am 6'1" and 250ish lbs. My chest measurements are typically 48 inches, waist is usually 40 or 42 and sleeve length is 35/36. I have not worn them outdoors in cold temperatures yet, but after wearing them around the house for several hours, I can attest that they are comfortable and will provide sufficient warmth. Good product for a very affordable price.
