What is the difference between "splashproof," "waterproof," and "submersible"? – Cascade Designs

SealLine products use three ratings to describe water resistance:

Splashproof: Withstands light rain and splashes. Only some of our products fall into this category. Suitable for use where light water resistance is sufficient, such as summer backpacking.
Waterproof: Withstands quick submersions. Most of our bags fall into this category and are suitable for canoe, kayak and rafting use where boats may tip, flip or be swamped.
Submersible: Withstands 1 meter of submersion for 30 minutes (IP-67 standard). Suitable for use in extreme and prolonged wet situations.

With such ratings, water resistance depends on the user carefully and properly sealing the closure. For roll-top closures, this means a minimum of three tight, wrinkle-free rolls. For zipper closures, the zipper must be completely and properly closed.
