I have 3 of these wallets and my husband and I both use these while we travel.  Not only does it help us lighten our load (we weed out cards and things we don't need when we travel) but the change compartment is great and helps keep our money from feeling too bulky.
I carry two while travelling overseas, one for foreign money and one for american money.  They are lightweight and a super great size for a smaller travel purse.  I've looked at other brands and this seems to work the best.
