good and versatile
Used to carry snorkle gear - masks, fins, snorkles and towels for 2 people plus snacks, cameras, sun block etc. Capacity is large enough for any day excursion. The back panel is stiff, ventilated foam so it holds the load quite nicely and with waist and sternum straps it's comfortable for longer distances. Capacity would work for overnight as well, and with the compression straps you don't feel like you're over doing it when not stuffing it to the limits - very versatile.
