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. ### ⭐⭐⭐⭐⭐ nice and warm.... *by on Reviewed in the United States December 18, 2025* they fit my son perfectly. the fabric is soft and easy for him to move around when hes outdoors walking or shoveling snow. very comfortable. and they really keep him warm. so it is a very good buy ! ### ⭐⭐⭐⭐⭐ Great for the price *by on Reviewed in the United States June 9, 2026* I used these while deployed and worked great. 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. ## Frequently Bought Together - SIMIYA Thermal Underwear Set for Men Long Johns with Fleece Lined Base Layer for Workout Skiing Running Hiking Navy Blue - Merino Wool Socks Casual Warm Socks for Winter Cozy Boot Socks for Men & Women - Alvada Warm Thermal Wool Socks for Winter Moisture Wicking and Breathable Cozy Boot Socks --- ## 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.jp/products/568898622-simiya-mens-long-johns-thermal-set-fleece-lined-base-layer](https://www.desertcart.jp/products/568898622-simiya-mens-long-johns-thermal-set-fleece-lined-base-layer) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-18*
