XTR4 is ZAGG's strongest and most technologically advanced screen protector. It contains graphene, one of the strongest materials on earth, and has been tested to be up to 11 times stronger than conventional glass protection. XTR4 filters blue light with Radiance Protection Factor 60 technology to improve eye comfort and sleep. The anti-reflective technology improves colour depth and vibrancy on your screen. In addition, XTR4 has an incredibly smooth, touch-sensitive surface that makes it perfect for gamers. XTR4 includes a dust repellent adhesive and an EZ Apply installation rack for precise alignment during application. At ZAGG we are conscious of our environmental impact, which is why the XTR4 screen protector is made from 30% recycled glass. The EZ Apply frame is made from 100% post-consumer recycled materials and the packaging is 100% recyclable. All these features have earned XTR4 FSC certification and the TÜV Rheinland Certified Green Product Brand.
