The Cressi 17 Litre Inflatable Float is a great buy as it is durable, covered by canvas with a inner bladder. Being inflatable, you can deflate it when not using it to store it away safely. The divers flag that it comes with is a world recognized flag to let boat owners know that you are in the water and to stay clear. There is a Velcro entrance underneath the float where the bladder is able to be taken out and you can also use this place to cater for a couple of weights. These weight's will keep the float in the up right position so the flag is sitting up and easily visible.
