Waterproof inner pockets
use
In order to fully experience a successful and, above all, dry use of our waterproof inner bags, it is of course important to close the bag completely and pull the zipper to the end.
pressure simulation
The video shows that up to 78 kg of weight was exerted on the inflated waterproof inner bag without losing air or stability. It would have been possible to do more, but we ran out of hands.
self test
-
Step 1
Open the zip of the waterproof inner bag slightly so that you can fill it with air and then close the bag.
-
step 2
Test whether the air that you blew into the waterproof inner pocket escapes through pressure build-up.
-
step 3
If no air escapes from this waterproof inner bag, this is an indicator that it is waterproof. Since air is less dense than water, it is easy to come to the following conclusion: if no air escapes from the waterproof inner pocket, no water can get in either.
