A buoyant, watertight enclosure designed to protect mobile devices from water damage while also preventing them from sinking. These accessories are typically constructed from durable, waterproof materials such as PVC or TPU, and often feature a secure locking mechanism to create a hermetic seal. An example would be a clear case used at a water park to keep a smartphone safe while allowing for underwater photography.
These protective cases offer peace of mind for individuals engaged in water-based activities or working in environments where accidental submersion is a risk. Their utility extends beyond mere protection; the buoyant nature helps in recovering the device should it be dropped in water. Originally, basic waterproof bags offered minimal functionality, but advancements in materials and design now permit full touchscreen access and photographic capabilities through the clear casing.
