Hi all, I'm travelling to Malaysia in a few months which will be my first international trip with my camera, and includes a few days in a rainforest.

It'll be dry season, but still wet, and I know to bring a rain cover and silica gel packets, but I'm looking for a day bag that:

Is not a backpack;

Is waterproof; and

Big enough to have my telephoto lens attached.

My current gear is:

Nikon z5ii

Tamron 50-400mm f/4.5-6.3 Di III VC VXD Z mount

Nikon Z 24-70mm f/4 S

Nikon AF-S 50mm F1.8G F mount

Keen to hear people's thoughts/tips/suggestions.
