RothcoGen III Level II Underwear Bottoms

Great product and quality

These are an excellent second layer above some next to skin poly bottoms. They are impressively warm and will wick well with the material and waffle.The bad part is the fit, that's the minus 1 star. The sizing chart is wrong in my opinion and you need a size smaller than you'd think. Although I did not find that to be the case for the top. These even when fitting right in the thigh, butt, and more or less waist are (for my XL) way way too tall. I'm 6'4" and I think my XL's (which I got in exchange for an XXL because the XXL was the right waist on the chart but was like stepping into a trash bag in reality) are probably about 2-4 inches too long in the rise and almost 6 or more inches too long in the inseam. I just fold the extra material up in the leg beneath the knee. There isn't a good way to get rid of the excessive rise because any fold seems to come out with the weight of the crotch. These are way too thick and roomy in the crotch. Unless of course you have a sack the size of a grape fruit.All in all I am please with the product and will use them over a L1, I just thought it was fair to mention sizing and comfort is a little lacking it seems.

I hiked for 14.4 miles over the top of Mt. Leconte and onto the Appalachian Trail in which half of the day snowed last weekend and was very warm. In fact, all I wore was the ECWCS silkweight pants (the top didn't come in time because of a mix up), the ECWCS level II thermal top and bottom, pants and a long sleeve shirt and a light jacket and a raincoat and pants to keep me dry. I was sweating and welcoming the cold snow blowing on my face. I originally started hiking with a thick jacket and after about 30 minutes took that off and just wore my shirt, pants and thermals for most of the day. I only put my light jacket and rain clothes on when it started snowing and I can honestly say that I could have probably even went without the light jacket because these thermals do an outstanding job of keeping you warm when it's cold. I believe the temperature was around 28. I bought a lot of equipment for this hike and I can honestly say this was one of the things I was most glad I bought right next to my Vasque breeze boots, Darn tough full cushion hiking socks, high sierra 45L pack, and my last minute purchase of Kahtoola microspike crampons (My favorite item, because while others were slipping on ice I could walk across with the confidence that I wasn't going to fall and hurt myself)

They run a size large at least. I wear a 35-36 waist and I had to roll the waist band a couple times and cuff the legs. They’re probably too loose still but they keep you really warm and they’re comfortable.

These are warm, and in the legs baggy enough for comfort and tight enough to not be constricting. However the crotch/waist is baggy enough that I could pull it up to my ribcage. Far too much fabric in the crotch and waist area. Like they expect me to be 7 feet tall. Other than that they are cheap and warm, just requires reshuffling to fit the excess cloth.

Great thermals. Wear these while sleeping while backpacking and they keep me perfectly warm and are very lightweight. They pack down very small and are warm for their thickness/weight. Also, they absorb less moisture and odor compared to cheap cotton thermals.The length is perfect as you can stretch the legs all the way down to your ankle. The size was spot on for me. I am about 6'3", 200lbs, and wear 34x34 pants and the large was perfect for me.These are a little bulky, however, and I probably would not want to wear these during the day unless I really needed them.

This product is super warm and comfortable.

Although not military issue, this seems to be built to mil spec standards. I use it for skydiving and am pleased with the fit and the warmth. This is the best pair of long underwear I have owned.I wear these directly under my blue jeans. Temperatures in the air can range from 20-40 in the winter time in Arizona and with free fall speeds of over 100 MPH that can get pretty cold. With these, for the first time in years my legs are warm.Rothco has been in business for years and seems like a trustworthy firm.
