Tough Groove protection for iPhone 11 Pro Max

This Case-Mate cover is built for the iPhone 11 Pro Max and delivers 10 ft. drop protection in a single-piece TPU shell. The iridescent splash watercolor finish shifts colour under different light while the grooved texture adds grip. Raised bezels guard the screen and camera lenses when the phone rests face down. Wireless charging works without removing the case.

One-piece fit with precise cutouts

The case wraps the 6.5-inch handset in a compact profile measuring 8.62 x 4.69 x 0.71 inches and leaves every port, button and speaker fully accessible. No belt clip, lanyard or screen protector is included, so users who want those extras must add them separately. The slim outline keeps pocket bulk low while still absorbing impact.

Sustained everyday protection

Impact-absorbing TPU disperses shock from repeated drops rather than cracking after a single hit. The tactile groove pattern resists wear from daily handling and keeps its iridescent sheen over time. Because the material stays flexible, button presses remain crisp and the wireless charging coil aligns consistently through months of use.

Questions about this item

How far can the iPhone 11 Pro Max fall inside this case and still be protected?

The Tough Groove case is rated for drops up to 10 feet, using impact-absorbing TPU material and raised bezels to shield the screen and camera from direct contact.

Does the iridescent finish trap heat or block wireless charging during all-day use?

The one-piece TPU shell is wireless-charging ready and adds only 0.71 inches of thickness, so heat dissipation and charging work normally without removing the case.

Will the precise cut-outs for the iPhone 11 Pro Max 6.5-inch model line up with my buttons and ports?

Yes, the case is moulded specifically for the iPhone 11 Pro Max 6.5-inch body, giving exact alignment for every button, speaker and Lightning port.
