I'm 6'6" with very wide shoulders (think Rugby player). I love my ENO double wide but have struggled to find a bottom side solution that is wide enough that isn't too heavy. So here'e is my bright idea----
I'm gonna buy two Space blankets 56x84 6oz total
I'm gonna bond them together with contact cement and duct tape and make a giant Mylar balloon. I'll leave a hole for a small rubber hose for inflation/deflation and add an oral inflation valve
If it holds air and I think it will (cause Mylar balloons hold air forever!), I'll buy Silnylon and make a cover to go over my balloon. Add some shock cord and I've got a man sized inflatable UL underpad.
Mylar 6 oz
Valve and little rubber hose 2 oz (guess)
Shock cord 1 oz guess
Glue and thread .5 oz guess
I reckon I'll be under a pound
Shock cord 5
Maybe $60 bucks
WHAT DO YOU THINK? How warm would it be.. I'm looking for 40degrees
I don't want to try it if it won't work....
