## Description

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

Review: Warmth Without the Bulk - 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.
Review: Great buy - keeps you warm and cozy! - 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.

## Questions & Answers

**Q: My son's 6 ft to 6 ft 2, and 140 lbs, large in undershirts and small in underwear. what size should i order for him?**
A: I'm 6'4" 180lbs, and was always like that as a teenager- large tops, small or sometimes medium bottoms. I filled out in my 20s-30s when I stopped skipping leg days, to be more like L bottoms, XL tops. Now, in my 40s, I'm a L top and 34"w x36L in Balmain, Gucci, Mike Amiri, Raf Simons, Ralph Lauren, Dulce & Cabana etc., actually I have an aunt who detests $2000+ for jeans and sends me Levi's every Christmas to make a point. 32 waist (well hips actually idk who wears jeans up that high but if it did I could actually wear a 28" or 30" but then I would need a 40"-42"L LOL 
Shop clerk, "Can I help you with anything sir? Mmm yes, I'd like to try on a 28Wx42L in these dodgy looking Walmart jeans please shop keep, I cannot seem to find anything on the rack 🤔?) 
Crazy. So I tried XL. Ha. No way. Maybe 1 leg in each of 2 pair, otherwise, mmmno. XXL was too tight (stretched too thin in my glutes, thighs & calves, and still too short -- looked like I was waiting for the flood. 3XL made all the difference. If he's 6'2" but under a buck fifty, XXL will give him a good fit + room to grow. I should have considered that - if I was 2 inches taller ( 6'6" ) these would be too short and then all the extra material that fits me as I am, would be higher up and therefore too small. So, long story short, XXL now [✓] If you anticipate him growing much more in the near future: 3XL. Good luck! 👖👕🧦🧤🧥🧣🛍️🩲🧢👟🥾⌚💎🎒👜👓🕶️

**Q: My husband is 6 ft 155 lbs. so tall and skinny. What size should I get him?**
A: My husband is 5' 8'" and weighs up to 175 at his heaviest.  I got a medium for him and the length was just perfect.  As the other person said, they fit like tights or like a good athletic shirt that I can't name but will stretch depending on the size of the person.  I would think a large would be needed for his height.

**Q: Im 6ft 5 and 219 what size should i get?**
A: I'm 6 2", 230 and I got xxl.    If I bought again I'd get xxxl.    They run small, and are a stretchy material that's comfortable but really hugs the skin. Pretty nice overall, though.

**Q: Im 5'5 and 180 lbs with a waist between 32 and 34. What size should i get?**
A: X-large they run small

### ⭐⭐⭐⭐⭐ Great base layer
*by J***N on January 15, 2026*

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.
