Belkin TruClear InvisiGlass
Belkin isn't too incredibly known for its screen protection, but its InvisiGlass screen protector is quite a unique product, and it's described as a flexible glass that has a hardness rating of 9H, which is just one mark below diamond.
It's a bit on the expensive side at $35, but it's a great option to go for if you want to protect your iPhone 6s from all sorts of scratches.
Plus, Apple recently launched a screen protection program in its stores that uses Belkin's InvisiGlass screen protector. An Apple employee can install one of these screen protectors for you using Belkin's own ScreenCare+ Application System. The program is currently open to the iPhone 6, iPhone 6 Plus, iPhone 6s and iPhone 6s Plus.
