This is the perfect size for my extensive trip to Europe. I'm using it as a wallet only... one locking zipper pocket will hold my credit cards and money...the other zipper-locking pocket will hold my passport only.... the cell phone fits in the non-locking pocket (in the back against my body) so I can take it out quickly without accidentally dropping my credit cards or passport.  It's light and the strap adjusts easily. I am feeling confident about carrying around my important "stuff" while i will be hiking and kayaking and sight seeing.
