Finally got to use my mahal in the mail and it was SWEET. The discs in the mail compartment, putter holder and mini older stayed really dry, as did everything in the out zipper pockets. My only complaint would be that the rain flap does not cover the out 2 larger pockets. I use one of those pockets to hold discs so they got wet but never thought to close the outer pocket zipper top which I have folded inside that outside Velcro pocket. And the other outside pocket hold my camelback.
The bag performed great and dried quickly
