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

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.

My husband say they are impressively warm without feeling bulky. The fabric is soft, stretchy, and comfortable enough for all‑day wear, whether you’re outside in freezing temperatures or just trying to stay cozy indoors. They wick moisture well and hold their shape after washing, which makes them a reliable winter staple. A solid choice if you want affordable thermal layers that actually perform.

Great base layer! We bought for a recent trip to Alaska and it kept my husband warm on the colder days of our trip. We haven’t had any issues with shrinkage with washing so far. Good tight fit for pairing under other clothing.

very good quality. thin and warm,not too warm. size is too small,would buy xtra large next time. no bulkyness . medium tight to skin and sleeves too short. very comfortable.

Used for skiing. Comfortable and kept me warm

These long underwear are nice because they are fitted and wrap you in a fleece like inside. They are warm and once I put them on I don’t want to take them off. Because they are fitted they look fine under clothes.

Excellent base layer for cold climate. Keep you very warm easy wash and dry. Great quality.

I am very happy with the purchase of these long Johns . They fit true to size and will stretch if need be. I put them on and could feel my legs warming up right away. Worth the money.

Muy buena! Mantiene el calor , bien a la talla

I've got about 4 pairs of thermals. These are the best. Took them to Iceland in November. They do the job. Warm, comfortable and good fit

Well packed and the products are of very good quality. I am very satisfied with the Fleece quality and delivery.

I purchased these for my son’s school camp and they lasted really well as he is really tough on his clothes. Not really suitable for freezing cold conditions but they were perfect for camping in the cooler months.

Very comfortable and you should definitely buy at least one size bigger then what you normally wear as they are cut small. In terms of warmth, I would say it’s not as warm as some other thermals I have had in the past.
