Product review: Waterproof Backpack - Overboard Classic
Since most of my travels I am on boats or close to the water and I usually carry all my equipment with me, drone, gimbal, camera etc., I thought it would be a good investment to buy a 100% waterproof backpack which is also suitable for longer "walks";)
After reading a couple of reviews, I opted for the Overboard Classic 20L backpack.

Great quality and comfortable carry.
