3 Ways to Keep Your Phone Safe in a Waterproof Pouch

Replace the plastic clip with a locking carabiner The default clip on most pouches pops open easily. A small carabiner with a screw-down sleeve stays shut.

Use a pouch with a twist-lock buckle Some pouches come with a proper twist-lock buckle that is far more secure than a cheap plastic clip.

Add a secondary waist strap A waist strap keeps the pouch close to your body during active use. It also prevents loss if the main attachment fails.
