Mens Thermal Long John Pants - Thermal Bottom Base Layer for Tshirts & Jackets - Lightweight Thermal Underwear Mens - Sizes up to 3X- Pack of 3

This three pack of thermal pants is great. The pack I chose had light grey, dark grey and white. They are made with a 60% cotton, 40% polyester blended waffle pattern, light to medium, thermal blend. These pants will work great under any clothing on a cold cloudy day. I normally wear an XL size in sweat pants or lounge wear. These pants are a large size and actually seem a little loose. If you prefer tight thermal underwear you might want to try a smaller size than you normally wear. These pants do have a fly opening in the front, but I might actually wear them around the house since it is just me and my wife here. They also would work well as sleep wear. Even though I live in a warm climate, I think I will get a lot of use out of these pants this winter.

Winter comes around every year and for much of the country it's just really cold for many months at a time. These thermal pants are somewhat like tights which are generally worn under something else like snow pants, jeans, slacks, or anything else you would normally wear but just aren't warm enough. So far I've worn these under my denim blue jeans while going out to a job site maintaining a professional and normal appearance but also staying warm standing outdoors in cold and windy conditions. They kept me much warmer than regular pants alone, but since the material is breathable I wasn't uncomfortable or sweaty. They stretch enough to fit most normal leg sizes and shapes, I accidentally got a 2xl and probably would fit a 1xl better, but if you don't like tight material the next size up still feels nice.. After a bit you just forget you're wearing them except you're not cold! There's no tag on the rear so no chance at it causing itchiness, plus the elastic at both ends feels great. I really like these thermals and it's great they come in a pack of 3 for no other reason that you'll need a few pairs of these to keep you warm this winter!
