I am doing a downwinda today and want to take my phone so that if it goes pear shaped i can call for help and also listen to the cricket on the way .Any suggestions (the earphones will be coming out of the bag too)
2 condoms - put phone in one let it hang and tie a knot add a second and another knot and put up wetsuit arm. I have done this many times 20+ for both phone and GPS and never ever had a problem iPhone buttons work through dinger as well.
It's simple and works incredibly well
