Have this Overboard (5L) - the name captures it well to - three times now in use had the kayaking. In each case, to keep my personal things in front of me to hand. Even in heavy rain and dive MTI kayak all items remained in Overboard dry. The yellow color is also a good eyecatcher on the water. The 5L volume rich with me for: change pants, shirt change, change socks, Smartphone, battery pack, Antibrumm, handkerchiefs, bread and butter, banana, pocket knives, smoked sausage, energy bars, card - easy.
