From the harsh environments of space to the most intense temperatures on the planet, to an accidental plunge to earth, the PHOOZY and our materials have been battle tested to provide the ultimate outdoor protection for your iPhone 11 Pro. PHOOZY allows you to stream your music via Bluetooth to your air pods or speakers and not have to worry about your iPhone X overheating in the sun or freezing on the mountain. With full access to the lighting port, the layered matrix technology shields your phone with military-standard (810G) protection for solar radiation, heat, cold, and drop. Did we also mention it floats - keeping your iPhone 11 Pro from sinking to the bottom. The PHOOZY is the only Thermal Capsule sleeve rated from 200°F to -32°F.
