Thermajohn Long Johns Thermal Underwear for Men Fleece Lined Base Layer Set for Cold Weather (Medium, Grey)

Warmth Without the Bulk This Thermajohn thermal underwear set has been an excellent base layer for cold weather. The fleece lining feels soft and adds a good layer of insulation without being too thick or heavy. I wore it under jeans and a hoodie on a chilly morning walk, and it kept me comfortably warm without overheating once I was moving around. The material has just enough stretch to allow easy movement, and the fit feels true to size for an XL—snug but not restrictive. What I especially like is that the set is lightweight yet traps warmth well, so it doesn’t feel like I’m bundled up. The fabric also seems to wick away sweat decently, which helps keep things comfortable if you’re active outdoors. After a wash cycle, it held its shape and softness, no pilling or shrinking noted. Something to keep in mind is that while this works great as a base layer, it’s not intended to be worn on its own in really cold temps—you’ll still want an outer layer. Also, the top is a bit longer, which helps keep it tucked in but may feel extra for some. Bottom line: A reliable, comfortable, and warm thermal set that’s perfect as a base layer for cold weather activities or just keeping cozy indoors.

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!

Well made and does it's job to keep me warm and comfortable.

Comfort, good quality

I was initially put off by how tight they were as my old cotton ones were looser and more comfortable. However, as I used them I realized the tightness was not so bad and was keeping me warmer because they were tight. Plus, the material was very comfortable and not scratchy.. Ultimately very happy.
