Tough Neoprene Bags
We have these really cool, black, neoprene bags which I use for everything. They're protective & tough so I use them to carry my Gopro & all it's gear when I travel or go anywhere. I use another for my Ayup bike lights with batteries etc. Another one is my makeup bag and a small one is for my contact lenses. They don't get dirty being black -but I have thrown the make up bag thru the wash quite a few times now -being neoprene they're kinda good in water! :) They dry quickly too.
When I pack a bike bag to travel by plane I've used them to put my tools & lube in and i know they won't bounce around and damage my bike being packed in the neoprene. I have one in the boot of my car with goggles, swim cap, earplugs & a cozzie -ready for a swim session anytime, anywhere.
I love the little "chain link" zipper puller.....it took me ages to do the technical drawing for it -but it was worth it.
