The problem with standard toiletries bags is that something invevitably spills in them: benadryl, conditioner, mouthwash, hand lotion, whatever. And it’s always impossible to clean up.
My dad really wants a mesh toiletries bag, like the kind of stuff dive bags are made from. Of course, that would get whatever nasty spill happens in your toiletry all over your other stuff. So it would need to snap out or otherwise live in a nice rubberized zip-up bag.
I feel like this should already exist, but I’ve never been able to find one like this.
