This is a basic, no frills bum bag that is a good size and very unobtrusive, which for me is a plus point. It is super lightweight, and folds into its own integrated carry pouch which is small enough to pop into a handbag or rucksack, to be whipped out when needed.I have found it particularly useful when playing golf, as all my essentials fit into it easily, and it doesn't get in the way. It weighs practically nothing, so doesn't affect balance when playing sport or running.The quality of the bag is great. It might be light, but that doesn't make it flimsy. It is very sturdy and well made, with good strong seams and a robust fastening, so it is unlikely to come loose or unfastened during wear.Overall, a great, good quality and well thought out product, and well worth the asking price.
