PHOOZY XP3 Insulated Phone Case insulates your phone in hot cold conditions to increase battery life up to 4X - like having your own climate control phone case (compared to not using a PHOOZY) New! Agion technology is integrated into our SoftTouch Protective lining to keep your PHOOZY cell phone pouch and your devices clean. Award-winning, patented materials and design easily slides in your jacket or pants pocket for complete protection while on the slopes or for all of your outdoor adventures. PHOOZY's NASA derived technology will not interfere with cellular, WiFi, or Bluetooth signals. PHOOZY's Anti-Sink, water-resistant technology acts as a life jacket for your phone, keeping it afloat if dropped into water. Disclaimer: The PHOOZY insulating cell phone case is not a cell phone cooling case or cell phone warmer for cold weather, meaning it does not cool down a hot phone or warm up a cold phone. It helps prevent overheating in the sun by reflecting solar radiation (heat) and extends battery life in the cold by insulating your device from frigid conditions. It is designed to increase the length of time your phone will maintain optimum operating temperature in both hot and cold conditions (compared to not using PHOOZY cell phone pouches), which can extend and preserve your battery life in extreme conditions. The XP3 Series features multiple attachment points and our all-new tether system, you never have to bury your phone in your gear again. The internal stash pocket is made for your cards and cash so you can ditch that bulky wallet.
