They are sprayed aluminum on 1 side, so washing would remove this, leaving only a plastic sheet, which would not keep you warm. **Q: What is the mil thickness of this compared to the regular ddity mylar sheet?** A: One of the product images says that they are 28 micrometers thick. That's about 1 mil. I've seen other ads claiming that the cheaper space blankets are 12 micrometers. This plastic is noticeably stronger than the polyethylene used in trash bags and painter's drop cloths. **Q: I know they are for outdoor use but any reason they couldn't be used as a travel blanket when flying?** A: While I've not experienced an emergency where I used these particular mylar blankets, I do recall that earlier versions of the disposable shiny mylar blankets were quite "crinkly," that is they were noisy. If these create that same annoying noise, your fellow passengers my not enjoy that disturbance. If, indeed, they are silent then their use aboard an airplane should be okay. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***Y on March 6, 2024* ### ⭐⭐⭐⭐⭐ Review *by A***. on March 29, 2026* ### ⭐⭐⭐⭐⭐ Review *by K***Y on August 6, 2025* ## Frequently Bought Together - World’s Toughest Emergency Blankets [4-Pack] Extra-Thick Thermal Mylar Foil Space Blanket | Waterproof Ultralight Outdoor Survival Gear For Hiking, Camping, Running, Emergency, First Aid Kits [Camo] - PREPARED4X Emergency Poncho and Mylar Blanket Liner - Waterproof, Wind-Resistant Green Outdoor Rain Poncho for Camping and Car Emergencies - LifeStraw Personal Water Filter for Hiking, Camping, Travel, and Emergency Preparedness --- ## 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/290760748-world-s-toughest-emergency-blankets-4-pack-extra-thick-thermal](https://www.desertcart.jp/products/290760748-world-s-toughest-emergency-blankets-4-pack-extra-thick-thermal) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-24*
