Our team of fellow paddlers designed this 20L waterproof backpack to carry and protect your belongings from getting wet when doing water sports. This 20 L backpack lets you carry your belongings and protect them from splashes of water and brief immersion. Perfect for kayaking, stand-up paddling, or light sailing.

WATER RESISTANCE TESTS: TEST 1: "PUDDLE OF WATER" The bag is resistant to shallow immersion for 8 hours in 10 cm of water. This test corresponds to a bag floating in a water-filled boat or to a brief fall into the water. TEST 2: "SHOWER" The bag is resistant to a shower of 450 L/m²/h lasting 4 hours. This test corresponds to heavy rains or splashes from waves.

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 (5L or 10L) placed inside a large dry bag (20L, 30L, 40L, 60L). 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 a SUP or a kayak equipped with fastening loops, enabling you to carry your belongings into the water and protect them.
