Haven’t used the bag yet but have been experimenting with packing it - we are travelling to the Arctic in September and needed a waterproof bag, and this seems to fit the requirement.
Maybe a smaller version that can serve as a “handbag” for keeping passports and other documents as well as phone/iPad/camera?

Thanks for the feedback! We're glad you're experimenting with the bag and that it seems to meet your waterproof requirements. We are always looking for ways to improve our products and your suggestion for a smaller version is definitely something we can look into. We will keep you updated on any changes we make. Thanks again!

Such a fantastic product for my surfing mad son
Copes with the wet clothes and is also secure

Sarah D.

Absolutely love my Crocpack, so much storage space and separate compartments which makes it easy to find everything, and so easy to carry

Thanks for that great review Sarah, love that you're rocking the summer with your new fave bag. Enjoy! Tim

Sally G.

Looks like it will be perfect as we hoped. Very practical.

Hey Sally, thank you so much for your review, I really hope you get a tonne of use out of your Crocpak®, I still use mine every day!

Helen L.

Fantastic bag great materials, great idea. Environmentally friendly and donations go to a charity. Large to medium bag, waterproof and looks great!

Hey Hellen, thank you so much for your review, and I really appreciate the fact that you highlighted some of our favourite brand features.
To be very honest, the thing I am most excited about with these two brands is the chance to give back via charity contributions. If the world is ever a slightly better place with the advent of Crocpak and Kaskade, then thats a good thing in my book.
Have a lovely holiday season!
