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: Helps while working out in the cold - I recently bought these thermal long johns for my boyfriend, who works in a cold environment, and they have been an absolute game-changer! Not only do they keep him warm and comfortable throughout his entire shift, but they also allow him to move freely without feeling restricted. The material is top-notch, providing excellent insulation without adding unnecessary bulk. One of the best things about these long johns is their versatility. He can wear them under his work uniform for added warmth or even use them as a base layer during outdoor activities. The quality is evident, and they have held up remarkably well even after multiple washes. Additionally, the fit is spot on, and he loves how they don’t ride up or bunch during the day. They are true to size and provide a snug yet comfortable fit that doesn’t hinder movement. Overall, I highly recommend these thermal long johns to anyone working in cold conditions or anyone looking for reliable and comfortable thermal wear.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Warmth Without the Bulk *by E***S on September 25, 2025* Warmth Without the Bulk This Thermajohn thermal underwear set has been an excellent base layer for cold weather.

A definite five-star product! ### ⭐⭐⭐⭐⭐ 5-Star Review for Thermajohn Long Johns – AKA My Cold Weather Survival Suit *by K***S on June 2, 2025* 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. ## Frequently Bought Together - Thermajohn Long Johns Thermal Underwear for Men Fleece Lined Base Layer Set for Cold Weather - WEERTI Thermal Underwear for Men Long Johns with Fleece Lined, Base Layer Men Cold Weather Top Bottom - Alvada Merino Wool Hiking Socks Thermal Warm Crew Winter Boot Sock For Men & Women 3 Pairs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/21814852-mens-j-t-m-1836](https://www.desertcart.us/products/21814852-mens-j-t-m-1836) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-05*
