194 reviews

As Seen on Shark Tank.  Introducing the new Apollo II Series from PHOOZY.  While it offers enough protection for your phone to summit Everest and still be able to take a selfie, the modern silhouette and materials are designed for urban every-day-carry. Our award-winning technology is integrated into adventure-ready form for the ultimate “city-to-mountain” crossover gear.  Our layered matrix of premium technical materials strikes an ideal balance between function and form for every adventure.

  • UltraShield Ripstop Skin with UV and Hydrophobic Coatings are no match for dirt, rain, lattes or snow.
  • New! Impactor Core 1.5 provides increased drop protection exceeding the 810G 516.6 military standard while still maintaining our legendary Ultralight and slim design to easily slide in your jacket pocket or backpack for complete protection.

      Great case for the beach No sand gets on it and it doesn’t overheat


      Works great, as long as you have room for it

      I run a lot and bought this to prevent the phone from overheating in the summer and getting too cold in the winter while it's in my hydration pack. Haven't been able to test winter yet, but so far so good for the summer - tested in my car on the passenger seat in broad sunlight, without Phoozy I got excessive heat warnings in minutes but with the case it didn't overheat. Only issue is that it's big, plenty of room for my Pixel 3a but makes it hard to fit in the pockets of my running skirt or hydration pack without some finagling. It's a tight fit in my pockets but does keep the phone from getting sweaty, or wet in the rain, so I do recommend it as long as you have room for it.

      Saw on Shark Tank

      I love it. Granted, I haven't used it in the way I need to yet, I'm excited to be able to go the beach with my phone safely. I can take my canoe/kayak without fear of yet another phone swimming with the fishes! Thank you Phoozy!

      Works great!

      This works great! It kept my phone cool all day out in the sun and didn’t run my battery down. Love this! The only thing I would do different is add a pocket for my glasses.
