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

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.

They are very firm fitting and they are very warm. I bought these to use under my pants and shirt for motorcycle riding in cooler temps. They work great and they are very comfortable:)

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.

As the owner of an Akita who is virtually weatherproof and likes his two walks a day. And as an interior trim carpenter who is often working an environment where I'm out in the cold, and then warmth of inside as a continuous cycle my search for the perfect thermal continues. The two keys to staying warm in cold weather is preventing air infiltration, while not dressing so warm that activity causes you to sweat.First, the good things. Both the top and bottoms are very comfortable. Although "large" was recommended, I went with medium and both the top and the bottom fit like a second skin. No bunching, they move with my body and I notice no creep in the material. Both garments appear well made, labeling is printed (a HUGE plus in my opinion) and very soft feeling. I'm confident that once I just wear them, instead of paying attention to their warmth purpose I'll forget I have them on. At rest, in the warmth of a heated house, they will not overheat you which can be a downside to some thermals in my experience.Now to the purpose. Warmth. This morning temp is 40 (f) with a "feels like" of 35. Light NW breeze. On our morning walk (more of a stroll, since the pup is getting up in years these days) I wouldn't call myself warm, per se, but comfortably cool. I estimate the bottoms will probably hold my warmth down to an outside temp of about 30 (f) but not much colder than that. Having said that, under moderate to vigorous exercise/work I'm sure they'll perform better. The top kept my torso (core) warm, with a cotton long sleeve over it, and then a regular shirt over that (and a medium weight jacket over that). Legs with just the base layer and a pair of cargo pants over, I could feel air infiltration. Not bad for what these are - a thin base layer. Though, not as good as some other thermals I've had (and am having a hard time finding again, bought them as military suplus).I'm going to be keeping these, they'll work on days like this. I can also see these as being a good choice on days that start out in the 30's and end in the upper 50's without overheating. The only reason I gave them 4 stars is because they still aren't quite what I'm looking for - which is a thermal that will perform well into the 20's with minimal overheating inside.

These were an early Christmas present for my husband. He loves them. They're not that thin,definitely not bulky. The lining is very soft. They wash well with no pilling of the fabric. They keep out the cold wind. He liked them so much, we ended up buying 4 more sets for our boys. They seem to run true to size.

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.

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

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!
