I was thinking of looking for a caving bag that I could use to carry wet dive gear from the pool to the club store. Our club store is not far maybe 70 metres away but you still have to exit the pool building, walk up the road, up and down stairs as well. This means that after the pool I am changed back into my day clothes and they usually get wet as bcd, fins and pool shortie are all dripping. I keep a rain coat handy to stop me getting soaked through at the shoulders but legs still get wet.
If I had a cavers style dry back rucksack with wide opening I could put everything in and carry it on my back while staying dry. That is cylinder, bcd, fins, the lot so bag needs to both wide diameter and strong. I was also thinking the caving back would double up for other carrying, such as taking my twin 8s to get tested when travelling by public transport. Might also be useful for stuffing gear in when car sharing to prevent the boot getting wet....
Other bonus would be a some sort of flap lid and ideally a waist strap to take some of the weight of the shoulders.
A quick google brought up quite a few hits, so advice on what is up to the job / where to buy from would be very welcome.
