Got this product for emergencies to stash in our hiking bags and my car. Wasn't expecting too much from them as they were so cheap, but glad to be pleasantly surprised. As there are 5 in the pack, I cracked one open and got in there, felt the heat from it straight away; within 2 mins I was toasty hot (had been feeling the northern chill prior to trying it out) so really think they will be useful to keep warm should an emergency crop up.
I gave it a good pull to test the strength (like one of the advert pics demos) it stretched quite easily with fair force, but didn't tear. Conclusion: not the toughest of material, but if you're careful that shouldn't matter as there is plenty of width to get in. Also long enough to cover up to top of head (I'm 5'8"). Overall, I think the product is good and will definitely do the intended job should it be required.
(Final pro tip: do not test it out with your cat in the room as the material does not withstand their claws when they get excited by the rustling sound! :D some gaffer tape will sort that one out and the test one has gone in my boot- you can get them folded back down by rolling the air out, but not back in the plastic seal bag they come in).
