Since the recent rash (get it, rash!

) of threads about butt burn and seats, I thought I would resurrect a subject brought to us a long time ago by either Derek or Soren (can't even remember if that's correct).
Anyhoo, there is this wallet made from ripstop nylon spinnaker cloth and comes from a company called
ALL-ETT. Holds everything you have in your wallet now but is
considerably thinner.
Here's a pic of the original version that I have (they have more varieties now):

I bought one about two years ago, use it every day, and I can attest to the quality and strength. There is no wear and tear on it at all. I have 12 cards in it, all my registrations and insurance papers (truck, wife's car, bike, and trailer), money, and the sucker is less than 3/8" thick. There are times I forget it's there and while riding, there is no pressure from a wallet like I had before.
An amazing product and only costs $19.95. Very happy with it and I highly recommend it!
