Description

Protect your belongings from getting wet when going water sports

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 using a paper towel. PLEASE NOTE: The external quick-access pocket is not waterproof!

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 look inflated once closed: this makes it more waterproof 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 a SUP or a kayak equipped with fastening loops, enabling you to carry your belongings into the water and protect them.
