Product Customer Reviews

This product is suitable for my use.
Already my second purchase of this product, to replace the old one. After 2 years the strips of fabric almost all broke at the same time. Daily use as a biker and diver. Very practical interior pockets. Large enough volume to fit a laptop and 2 or 3 items. I really like.
Very clean and great content
Possibility of adjusting the size according to the filling.
The system and the material are well thought out but in terms of waterproofing in the rain it is perfect as long as it is not immersed in water for too long in a lake. I haven't really done the test on this last point. On the other hand, no water closing, you have to remove the air to properly close it when it is filled.
Test it in real life in Malta. Towels in the bag and flip-flops hooked up, and off you go! Super waterproof, floats and stays comfortable in range.
Used it as my carry on baggage - from air to sea and back! Kept my drone and camera gear safe from the water. Can be improved by having options/accessories like waterproof padded shoulder straps and removable/adjustable internal padding for things like camera gear.
waterproof bag of good capacity it has its small interior pockets very practical I love it
Great product that I used during my stay in Polynesia. Suitable for maritime craft, even in the event of unexpected showers. I recommend.

Additional Product Information
Composition
Main fabric: 60.0% Polyester, 40.0% Thermoplastic Polyurethane
Precautions for electronic devices
Electronic devices are fragile and valuable. We recommend doubling up their protection by putting phones in waterproof pouches inside dry bags. Cameras can be put in a small dry bag (5 L or 10 L) placed inside a large dry bag (20 L, 30 L, 40 L, 60 L). Ensure your bags are closed and check water resistance regularly before your session using a paper towel.
Fastening system
To ensure good water resistance: 1/ roll the top of the bag over carefully 5 times, folding tightly over the width of the strap 2/ fasten the central buckle 3/ fasten the side buckles Leave some air in the bag. The bag should appear inflated once closed: this makes it more watertight and allows it to float if dropped in the water.
Attachment on a stand up paddle or a kayak
The 2 compression straps on the body of the bag can be used to attach the backpack to an SUP or a kayak equipped with fastening loops, enabling you to carry your belongings into the water and protect them.
