The pain in my rear has finally convinced me to try and remove my 'costanza-sized' full wallet from my back pocket and go with a front pocket option.  Of course it will mean some trade-offs in limiting to only the most essential items and sacrificing the convenience of having anything and everything at the ready.

Saw a good deal on this wallet and decided it was a low price to pay to start the process.  For being such an affordable wallet, the material and construction were decent.  Next, I had to decide what was the absolute minimum that I needed to carry.  My drivers license, four credit cards, three store membership cards, 4 thin health insurance cards (mine and family), 3 other thin membership cards.  Packed in a little tight, and a little tight getting some of the lesser used ones out, but so far so good.

I was able to put in about 7-8 folded bills into the center, not sure if I'd really want much more than that, and getting the cash out also presented a little finesse.

Thus far, I'm generally happy and this thin wallet is probably about 1/3 to 1/4 the thickness of my (normal) old one (perhaps half as thick if I were to similarly pare down my old one), and I carry it around in my front pocket.  My front pocket is getting a little more cramped as I carry my car keys, but it's ok.  The one area that I feel still a bit worried about is the limit of the cash pocket - I definitely should not keep as much cash as I used to in my old wallet, but the practical limit and less convenient access may lead me to try another thin wallet style, perhaps one with a paper money clip or middle billfold storage.
