Waterproof phone cases, while they may provide great protection, almost always negatively impact phone usability. A pouch design like the Kona Submariner allows you keep your phone dry when you need to and retain full usability when you don't. The Submariner has clear windows on either side, a secure locking mechanism, and an adjustable strap. The IPX8 rating means that it won't provide any drop protection, but it will keep your device dry up to depths of 100 feet (30 meters). Plus, you can make it float by simply squeezing the case while closing. If you notice any tears or the closure not working properly, Kona offers a 5-year replacement warranty for free.
