The front pocket on the other hand where you might be inclined to put your easy to reach items wallet phone etc is not fully waterproof

This is not outlined in the product description and someone could get caught out and not have a good day if their phone is in there

I havent been able to test the waterproofing but i have filled the bag with air and sealed it and it doesnt let any air out i initially returned one as it had a couple of small holes that leaked air during this test
