We found this bag to be really handy when we go abroad and tended to put the basics into it when we went kayaking or to the beach etc. The bag is light and folds up small. It is quite comfy to carry and did not let water in even when the kayak was clearly flooding! However, very soon into the holiday the lining ripped as if we had overfilled it (it wasn't too heavy in my opinion) and so obviously was no longer water tight. I usually like overboard products but have now replaced this with one of the stronger, tarpaulin-based overboard bags that are in tube form, rather than these weak flat bags.
