Hey guys;
I have an unopened survival blanket that I have been carrying on all backpacking and day hikes for more than 20 years. Since it's unopened, I have always assumed that it's still usable, but I've been reading that these things can deteriorate even in their sealed packaging.
Regardless of whether my blanket is still usable; are these things even worth carrying? I have been Googling recently, and it seems that the usefulness of these survival (space) blankets is questionable.
So, should I purchase a bran-new one to carry with me on day hikes, keep carrying the old one, or just toss it and forget about it.
I always carry extra gear when I'm on the trail - even for just a day hike.
Thanks for your input
