All DRY PAK items have cam lock clips on top that hermetically seal out water, sand and dust. Simply twist the knobs upwards to open; twist back down to seal. It's that simple! All cases are securely ultrasonically welded to the top clips, so there are no parts to lose. What is TPU Many of the clear DRY PAK items are constructed of a hi-tech thermo-plastic-polyurethane. It's approximately 10 times stronger than vinyl and has incredible resistance to hot and cold temperatures. Sounds transmit through TPU with less than 5% loss of volume, making it the perfect choice for phone and VHF radio cases. We use optically clear materials for our camera and camcorder cases.
