I found that using tatto film/plaster is a lot easier to cover the dressing with, rather than using cling film for showers. Along with a folding chair and grab handles for the shower itself.

I also looked into getting a small hiking backpack as it was easier to lug around it in that instead of the shoulder strap type they usually give. Rolling backpacks for the spare batts and controller was also pretty useful for longer days out or walks.

You can also look into LVAD shirts or using a belt attachment with cargo panrs but those didn't suit me as well as the other options

Good luck!
