Glass XTR4 is the strongest, most technologically advanced screen protection from ZAGG. And now, we’ve added graphene, one of the strongest materials in the world. XTR4 has been tested up to 11x stronger than traditional glass screen protection. Glass XTR4 filters out blue light with Radiance Protection Factor 60 technology to improve eye comfort and sleep. Anti-reflective technology increases color depth and vibrancy on your screen. And XTR4 has an incredibly smooth, touch-sensitive surface, perfect for gamers. Glass XTR4 has an anti-dust adhesive and an EZ Apply installation tray, so you get precise alignment when you apply XTR4 to your screen. At ZAGG, we’re conscious of our environmental impact, so Glass XTR4 screen protection is made with up to 30% recycled glass. The EZ Apply tray is made with 100% post-consumer recycled materials, and the packaging is 100% recyclable. All this has earned XTR4 FSC certification and the TÜV Rheinland Certified Green Product Mark.
