I've got a few shoots coming up where I'll be on set all day, and I'm trying to figure out the best way to carry my essentials - power bank, pens, small notebooks, maybe an intercom, a mini water bottle, meds, sunglasses, etc.

Shoulder bags are fine, but I kinda prefer the look of waist packs. Are they actually comfortable for long days on set? Any recommendations for durable, functional ones that can hold all this stuff?

Products available in India would be preferable.
