I've never done the tarp/bivy camping thing and having limited resources, I'm trying to decide if I spend my money on a good quality tarp and make a bivy out of tyvek or do I get a cheap sil-nylon tarp and a nice bivy. Any thoughts on this??
Basically, if I have $150 to spend, how do I spend it when it comes to tarps/bivies?
To add to the mix, I am 6'-4" and need something that will fit my height and maybe even my winter sleeping bag.
Thanks!
