Wow. I'm impressed --- and surprised --- that at 6'4" you fit in a Gatewood cape (as a shelter I mean, not an issue as a poncho).

I'm somewhere between 5' 9" and 10" (probably shrinking down close to the former now), and find that with a thick air mattress I have to be careful not to get condensation on the end of my sleeping bag in my Gatewood cape.

But if it works for you, it works, so --- great!
