OuruikiaMen's Thermal Underwear Pants Modal Thermal Bottoms Long Johns Pants Underwear with Separate Pouch

It's been something of a holy grail to find thermal bottoms that strike a perfect balance of warmth without being hot. Part of the genius of this product is its pouch design. Not only does it keep the parts separate that tend to get hot and stuck together but mesh has been added in strategic spots.The other benefit is the material itself. I generally prefer cotton for undergarments because synthetics, no matter how "moisture-wicking" they claim to be, tend to reflect heat. Modal in this application is ideal. At first, I wasn't sure how much I would like the temperature-neutral feel to it. I liked how thin and lightweight it was but compared to cotton, I worried it might be too cool. Not so! It's definitely cooler but never cold. It does its best work by essentially becoming a sort of second skin. It feels barely there but eliminates chill and drafts. I thought I would probably only wear these on mild days and switch to warmer thermals when it's really cold but they're now my go-to for both. I've just bought another pair.Finally, the fit is excellent. At 5'8 and 155 lbs and well-endowed, the medium fits perfectly. Other reviewers have complained about the pouch design but I've found that it just takes some getting used to. Unlike Separatec and underwear that adds separation between all the parts, this product effectively adds material between the scrotum and thighs. Then there is an outer flap that prevents chafing against the inside of one's pants. In my experience, everything stays put - which means it also stays cool and dry while everything else stays warm.I wish this brand would make regular underwear, like boxer briefs, with this same design and material! To date, I've found nothing in the way of regular underwear that works or feels as nicely as these.

I bought these to provide extra warmth under my cloths during the winter weather. I was looking for long underwear that provided good support for the nuts and bolt so I don't have to wear underwear underneath. These do a great job. They don't provide a lot of insulation if working outdoors during very cold weather, but they are great for wearing under cloths around a chilled house or office. They are so comfortable that I have started sleeping in them. I have no trouble with things staying in place in the upfront pocket. I will be buying more.

They run very small so I'd recommend ordering up a size.

I got a medium pair of the white ones and was surprised how soft and comfortable they are and, despite being rather thin, are toasty warm. I'm unsure how durable these will prove to be, but I've ordered four more in different colors and will be wearing them on cold days during the winter here.

I liked these when I first tried them on. The material is nice. The bulge is initially good. Things will pop put, if you sleep in them and action happens, which isn't all bad. After wearing them for a day, I found that they didn't remain snug in the male department, which is really what I wanted in the first place. I wanted long johns that didn't require me to wear underwear under them. As the day went on, I sensed that I needed underwear underneath to provide the support I appreciate.

I bought these as pant’s liners for a smooth additional layer under pants for working in a cooler office. Tired of the saggy crotch long underwear, I tried these. These are lightweight and not your longjohns for winter weather outside. But as an extra layer under dress pant, they are perfect! Horizontal fly is very handy for us left-handers. The circle cutout is for fly access and not so much for separation of parts. 35” waist, 36” legs, the large fits perfectly. So nice I bought three more. They also double as a lighter exercise tight. Not compressing, but comfortable!Update: Now it’s January and I’m back to buy more so I have enough for all week. Very comfortable, they hold up to weekly washing and are my go-to when living/working in chilly temperatures.

I got these pant after reading thr reviews. Showing they were good thermals. Once after trying them they do not keep you warm.

These fit tight not like the baggy long johns of old. Thin but not too thin. Good for a thin first layer
