Put vulnerable papers and electronics in a tested protective layer rather than assuming a bag is waterproof.

Begin with the real constraint
Put vulnerable papers and electronics in a tested protective layer rather than assuming a bag is waterproof. The aim is a small setup you can actually complete, not a larger collection of equipment. Lay out what you already have and notice the step that creates friction before changing anything.
Check the fit before going further
Check closures, seams and the forecast for the specific errand; leave a walking or bus option. Conditions and specifications vary, so treat this as a question to verify with the relevant maker, venue or source when it applies. A quick trial with the actual objects is more useful than a promise based on a photograph.
Finish where the next session begins
Dry the bag after returning so the next trip does not start damp. Take a moment to check that the result is accessible, safe for your situation and simple to repeat. If it still feels cumbersome, reduce the scope before adding a new purchase.
