Waterfield Designs has released two new slip cases for iPhone, and one in particular has the potential to flip people in the no case camp. Their Suede Jacket is a super-simple, minimalist pouch case with a handy side pocket for your Bluetooth headset. People that don't want a case for whatever reason will appreciate its ability to protect the iPhone from scratches when you toss your iPhone in a bag or a purse.
The Suede Jacket isn't suede but is built from a thin, stretchy mesh material with an optional back pocket that is large enough to securely hold most small to mid-sized Bluetooth ear pieces and plenty large enough for ear buds. When it's empty, it lies flat against the Suede Jacket and you hardly notice it's there.
