Must be really getting old now eh? Well, duly found these on line and they arrived well on time, and they fit my old fat but wrinkley torso and extremes very nicely... No fault at all..Thanks guys.. ### ⭐⭐ Nice and toasty but only if you're an Oompa Loompa (now updated) *by M***S on Reviewed in the United Kingdom on 15 January 2021* The quality is pretty good for the price and they actually are thermals and not something that claims to be. This is when things get weird, I'm 5'6 32" waist but chicken legs (short and skinny), these long Johns are very tight and too short in the legs, they end about three inches short of my ankles.The gusset (gusset hehehe) sits too low and is too tight but the waist is baggy as hell! They literally fall down by themselves exposing my winky, that made my Mrs laugh so hard she peed herself - I now refer to her as 'Tena Lady'.If I try to get them to sit properly around my family jewels the legs end halfway up my shins and the waistband becomes a chest band - Who or what were these things designed for?All in all, they're warm but wonky.Update: Both pairs have now been washed, 30 degrees gentle wash, and dried on the line. Now the legs are even shorter and the ankle cuffs are at my knees like a Victorian Boxer, they're even tighter but ironically constantly ride down and bring the crutch down my thighs making me waddle like a duck with hemorrhoids. These would be great for a clinically obese 5 year old with legs like twigs and enjoys being tripped up by a baggy gusset.Avoid. ### ⭐⭐⭐⭐⭐ Perfect *by J***E on Reviewed in the United Kingdom on 24 January 2020* I have given these a test in very cold weather and they are brilliant, although their thin they do provide good insulation and to me are well worth the price. I did order a size larger and as expected they fit perfectly. I will buy again when I need to --- ## 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.vn/products/80643927-heatwave-thermalwearheatwave-pack-of-2-mens-thermal-trousers-long-johns](https://www.desertcart.vn/products/80643927-heatwave-thermalwearheatwave-pack-of-2-mens-thermal-trousers-long-johns) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-21*
