MYOG wallet here

For everyday use I have an older model rip-stop nylon All-Ett wallet that's the best wallet I've ever had. Very thin and a perfect layout for my needs. I think I've had it about ten years and it holding up just fine.
On the trail I use a Z-Pack Wallet Pouch that's perfect for the few cards and limited cash I carry on the trail.
I wish I still had it together like Dan and could forgo a wallet on the trail but age and a trail name of Still Lookin' requires me to resort to more secure measures.

"All I need is a way to keep driver's license, medical card, and one credit card dry in my pack."

@ Michael:
Why do you need to keep these 3 items dry?
How does having them wet, damp, or moist hurt their performance?
