Waterplouf

The rain does not wet the Telephon inside the zip is sealed. The seams are not, by cons, but rain does not pass, anyway. Tested on the bike during this summer rotten.
Foams games allow to obtain the proper thickness. The screen is touch. It's all good.
Only flat, when it rains, I mist under the plastic. As soon as it stops raining, we open the zip on the top for ventilation. Or wipe.
