I've used this daily for a couple of years now.  Initially I got it because i wanted a wallet that would hold my passport.

Pros:
- Extremely thin, flexible and light
- Water & sweat resistant
- Durable: no undue wear of fabric or stitching
- Well organized with useful pockets

Cons:
- Fabric is very  stiff and 'crinkly' at first. It has softened and quieted up nicely, however.
- Fabric is slippery.  Makes it easy to get out of pocket and fall out of pocket. Cards fall out of pockets easily, though this has diminished somewhat with use.
- Prone to permanent creasing

I'm very happy with this item.  I have used dozens of wallets and  think I'm most happy with this one.  Main complaint is that cards have awkwardly spilled right out of the pockets in public upon opening.  This could be easily alleviated by sewing a small triangular flap over the corners of the card pockets, preferably out of a stretchy fabric like Lycra.  I had another wallet that used this and it worked very well, allowing access while restraining the cards.  Are you listening All-Ett? The wallet doesn't have much rigidity, which is a blessing and a curse.  There are two currency pockets, one normal 'Dollar' size near the top and a full depth one behind.  This full depth pocket is extremely useful for larger items like foreign banknotes including Euros, and separating higher value bills from lower value.  Banknotes from both pockets tend to migrate toward the top which is annoying. The fabric has lost a bit of it's slippery with use...I considered using a rubber band around the outside to keep it in pocket but that hasn't been necessary.  I also considered painting the outside with silicon sealant thinned down with vinegar to give it grip.

One great thing is that there is a small slot formed between the card pockets that's perfect for my micro wallet pen.

Initially I wanted this model to increase passport carry options while traveling.  However I always use an under-the-clothes pouch for this and haven't really had occasion to use it, though the All-Ett makes a great supplemental day wallet because it's so thin and light.  So I'm eyeballing another All-Ett with four card pockets instead. A passport fits nicely into one side of the deep currency pocket if needed.  Now...what to do with that damned huge International Driver's Permit...

Overall the Traveler's Wallet is great. Docked a point for slipperiness and maybe a tiny bit overpriced.
