We’ve looked at a lot of phone cases with wallet functions, but none is as configurable as the HoldTight iPhone case from Felix. The HoldTight has a backplate that snaps out of the case. You arrange the seven bands (3 vertical, 4 horizontal) into the configuration that will best hold what you want to carry on the back of your iPhone. It can be as simple as two bands to corral your headphone cable to multiple bands to secure some cash and your ID or credit card to the back. Once your wallet is configured, put the backplate in the case and snap it on your iPhone. The HoldTight is available now to fit iPhone 5/5s; the iPhone 6 case will be shipping at the end of 2014. You can choose either a white or black phone case with either blue, green, orange, pink, purple or red bands, or you can choose black or white monochrome versions. The HoldTight case for iPhone 5/5s is available now for $29.99; the iPhone 6 case will be $34.99. Expansion packs of the HoldTight Bands with two extra plates and seven bands each of two colors are available for $14.99. Learn more at Felix.
