The dry bag from the Pinguin brand is made of durable nylon and has taped seams, which guarantees that water and other impurities do not get into the bag. You can use the bag both in the boat and in the suitcase for better organization. Vibrant colors make it easier to orient at dusk. To properly secure things, it is necessary to roll the top of the bag 3 times and then fasten it with a buckle (the height is given from the base to the top of the bag).
