Zagg iPhone 5s Screen Guard
If you plan to go without an iPhone 5s case in order to show off the design and your color choice, you may want to buy an iPhone 5s screen protector from ZAGG.
ZAGG's Original through Extreme options offer protection for the iPhone 5s display. The Extreme iPhone 5s screen protector should help keep the iPhone 5s display safe from shocks and some drops.
