HealthyLine - Thermal Foil Sauna Blanket (Pack of 50 pcs) - for Detox & Weight Loss, Far Infrared Therapy, Survival and Preparedness - Retains up to 97% of Body Heat - 64in x 84in Mylar Sheets

I don't know that I bought enough brands to find much difference in space blankets but these are as advertised. they can tear but so do any of the others that I'veI bought in the past. I need a bulk pack because I use these to cover things like car seats when mechanics are getting in, or my clothes smell like fragrance and I don't want my car to smell like fragrance... And to line or cover all the stuff I don't want to end up smelling like what I'm near, because I am fragrance sensitive and chemical sensitive. Odors go thru plastic bags--and plastic bags have their own odors. These are plastic (so they don't tear like tin foil) but the foil costing mskes them odor-proof. I make baggies with foil tape to cover gently-used pillows when traveling (with anither cotton cover over it for strength, stuff like that...and though I can often wipe and reuse sheets if tbese, I also don't feel as bad about disposing of them when I don't want to carry dirt or stink with me...yeah wasteful, but it is hard to live with my sensitivities, I'm doing the best i can. I wish there were less fragile foil blankets for being able to easily wash--sometimes they are disposed of because they got torn up in use, but they make it thru as car seat covers for a trip to mechanic.

Wonderful product. Very durable. Had one get wet and hung it to dry. Storm came up and whipped it around - even across sharp surfaces and it didn't have a single rip in it. Used one for camping beneath my light weight sleeping bag directly on the ground and though the temp dropped, I was toasty. Great for covering flowers when frosty night in the forecast. Protected my sensitive summer plants even when we dipped below 30 a few nights in a row!

I use these for my Sauna blanket! Such an efficient and sanitary way to use! Worth every single little penny I paid! Will continue to buy!

Used these sheets clipped on an old wooden frame (from unused leaf collector box) to make a sauna that works wonderfully. The sheets are a good large size and are holding up quite well. Originally bought these to provide insulation for our blow up bed that we use in the car trailer at races. The bed became miserably cold every night, but a sheet or two of these under the pad helps immensely.

These are a little on the thin side, so be careful when unfolding they will tear. Otherwise, great for lining our sauna beds.
