Thes are the warmest, thinnest, and most comfortable long johns I have ever owned. I bought 2 more pairs from the same manufacture for just the bottoms but, they were different and was to loose. The top was too tight but, is has to do a bit with my gut. I'm going to keep an eye out for a discount on these an order more when the price comes down. Don't get me wrong, the price was reasonable, I'm just cheap and watching my dollars.

I'm 6 foot at190 lbs and these fit perfectly. I was impressed by them considering the price. They have lasted 4 cold months in a deployed environment and are still in great shape. I even wore these under mt running gear and usually run 3-8 miles and these didn't give me any chafing or anything like that. No issues with the material being itchy or having an odor like some cheap clothes can sometimes have. --- ## 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.fr/products/572298089-simiya-mens-long-johns-thermal-set-fleece-lined-base-layer](https://www.desertcart.fr/products/572298089-simiya-mens-long-johns-thermal-set-fleece-lined-base-layer) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-08-27*
