Smartskin Condoms for Smartphones are soft and stretchy plastic skins that cover your device to protect it, while still retaining full touchscreen capability and 98% camera clarity. The skins slip on and stretch to fit, and sealing tabs are provided to stick over the remaining area.
Useful for last minute protection from rain and sand. This looks nicer than my current sandwich bag solution.
Available for a range of popular smartphones from Firebox.
