It’s fabulous

Paul W.

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

Tuff AF, super keen to hit the beach with this bad boy. Love the eco aspect of this company, mark my words I will be back for more kit

Hey Billy, thanks for that cool 'AF' review ,) We were super conscious of delivering a product with as many 'eco green ticks' as possible. It's not perfect yet, but we wont stop till we get there. Thanks again mate.


This bag is THE BEST! It’s much bigger than I expected, and has an internal pocket.
I purchased for a day at the snow, it’s Definatley waterproof, and the locking system is very cleverly designed. The price point is great, this will be my go to gift for birthday and Christmas, and I will probably buy it in another color, and browse the website to see the range of other things.
I must mention the delivery and personalised service with emails was five star.

G'day Tracey, thank you so much for that kind review! Oh days at the snow sound awesome, and Im glad you love the locking system, took some work that one ,) Hope to see you back when you need your next gift, we've got a heap of awesome things coming for active go getters like you. Cheers again. Tim
