Thermajohn Long Johns Thermal Underwear for Men Fleece Lined Base Layer Set for Cold Weather

Bought these for a spring camping trip with 30 degree nights / 40 degree days & raining throughout. Kept me very warm - great base layer/layering. Very comfortable and soft, fits well. So glad I had them!

Bought this thermal set for my teenage son who’s spending a semester in a cold country, and he loves them! He’s 5'9", 175 lbs, and the medium fits him perfectly—snug but not too tight. The fleece lining is super soft and keeps him warm without being bulky. Great as a base layer under pants and hoodies. Definitely a must-have for cold climates or winter travel!

I never thought I’d be this emotionally attached to a pair of long johns, but here we are. The Thermajohn Thermal Underwear Set is like a warm hug from a teddy bear who also happens to be a professional insulation expert. Seriously—this fleece-lined base layer has no business being this cozy.I put them on during a cold snap and haven’t looked back since. I’ve worn them under jeans, joggers, and even pajama pants (don’t judge me). I’d wear them to work if I could. They’re warm but not bulky, stretchy without being saggy, and soft enough to make you question every other piece of clothing you own.Also, shoutout to the waistband for staying in place and not playing “let’s roll down every 10 minutes.” These long johns understood the assignment.If you’re looking to brave the cold while feeling like a warm cinnamon roll, these are it. Buy them. Your frozen thighs will thank you.

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.

Why did you pick this product vs others?:Bought this set for my husband to wear on a business trip. He loved them, said it was super comfortable and helped keep him warm in windy cold weather.Value for money:Great value for the cost.

These pajamas keep me very warm all night and since I got them I have slept through the night for the past two weeks now. I haven’t done that in over 10 years. They’re light and soft and I can move around very easily. The price was very good also. The fit is good and they seem to be very durable so far. Glad I bought them.

Great quality, fit and kept him warm
