Stashbelts is a physical product startup that aims to make the best moneybelt you can buy.
The product is a regular looking belt with a slot for a USB key, and a zippered compartment in the back that can hold SD cards, documents or cash. I use one as my main belt, no complaints.
A friend of mine started this company after living in Kenya and finding cheap leather and good craftsmanship.
I haven't told my friend yet that I'm submitting this, but I'm sure he'd appreciate feedback on the site and how to market the belts.

Most USB sticks are fairly fat compared to the connector. This makes for a slight bulge in the stash belt.
