I had a wetsuit made with thigh pockets and I want to buy a DSMB that will fit in one of them. This means it has to be no more than 17-18cm (6.5 - 7 inches) across and also roll up fairly tight. This is a bit skinnier than most 4.5 - 6ft DMSBs which tend to be 20cm (8 inches). Does anyone know a decent DSMB that is at least 4.5ft but narrower than the standard and that might be sold by someone who ships to Australia for less than an astronomical rate? If some one could point me in the right direction I'd be grateful.
