  • Very Warm, Very Comfortable, Very Well Made
Size: X-Large Color: Black
I have now bought three pairs of Thermajohn Long Johns for Men and two pairs of Ladies. They are very warm and very comfortable to wear, with a smooth surface layer which helps outer clothes slide over easily. The inside is low-fleeced and very warm. These are not bulky and combine the the best of all long underwear objectives in my opinion. They wash super well. However, I strongly suggest that you purchase them one size up for both men an ladies. I am not an XL guy but the Large was too snug. The XL, both the top and the bottom, fit me perfectly. I am 5'10", 185 lbs. ... show more

  • Solid buy
I love the feel of the liner. I ride year round and they added a good bit of insulation under my armored denim and my rain sleeve. Fits true to size, stretchy so they can fit skin tight comfortably, and they wick sweat a bit.

  • Pilltastic
Bought based on a recommendation from a friend. The material is supremely comfortable.... like wearing a second skin suit made of silk. Warmth so far is good, but I'm only wearing them in a chilly house. No idea how they would perform in outdoors cold (I bought them for lounging). Sizing is spot on and there is enough elasticity that they don't feel restrictive. However.... the pilling. Dear god the pilling. I washed them on gentle cycle, alone, immediately after receiving. Dried on ultra low. No noticeable pilling out of the drier, but after wearing for about 3 hours (nothing worn over them) they are covered in pill balls. I don't really understand why because normally I see pilling on high abrasion areas of clothes. These do it all on their own. For the price these are pretty excellent, but I don't expect them to hold up to long-term lounging. ... show more

  • Warm as Toast
These thermals are excellent quality. They are very lightweight, but provide excellent insulation. I use them for cooler days when I ride my motorcycle and I stay warm as toast. They launder well and at this point, I would say the longevity will be excellent as well. They wick perspiration very well, so they are comfortable when the weather warms up also. The grey color looks very nice as well. Good product! ... show more

  • Solid material
Size: Medium Color: Black
I work in a warehouse that ranges from -20 degrees Fahrenheit to around 40 degrees. It’s cold in there. I’m picking ice cream and meat or produce and groceries in the freezing arctic cold. These were my savior of cold aches after my shift. My joints would be all cranky after the shift but no more. These keep me nice and warm, and honestly maybe a little too warm at times if I’ve had too much caffeine. Don’t restrict my movement at all, and they’re super low key. I should’ve bought a large though: I have a large torso but a short build. I’m 5’10” and my torso is a little bit longer than others, making my legs just a little short in comparison. The legs were also just barely not long enough for my liking but no discomfort. Overall great buy, functions well, and I will continue to use this baby to stay warm ... show more

  • Great product but runs a little small
Size: Large Color: Black
Just opened them and tried them on, was a little worried about the noises it made putting it on but I’m assuming it just needed to stretch out a bit (no tears). However, I got the large thinking it’ll be a good fit for my preference considering I’m a 32 waist but I should’ve sized up further. I’m sure it’s normal for long John’s as it’s close to my wrists and slightly above the ankles but just wanted to state that if you like things a little looser then size up twice 👍 Without wearing it, I still feel like these are definitely enough to keep you warm and I’ll be trying them out tomorrow in 30-40 degree weather so I’ll see if I remember to update this lol ... show more

  • Very warm & comfortable
Size: Large Color: Navy
Very warm and comfortable. They have good stretch, so they're not too tight. So far, I've of the best brands I've tried. Cheaper than Under Armour, but maybe better.
