Hi there. My girlfriend is hellbent on getting a Quick-Pitch En-Suite shower curtain thing: https://www.backwoodsoverland.com/product/quick-pitch-quick-en-suite-aluminum-box-unit/ I've seen them in a bunch of Australian off-road videos, and they look really cool. I'm ready to pull the trigger, but now I'm debating whether to get the soft case, or the aluminum box. I'm leaning towards the box, but I'm curious about wind noise, etc. I'm also thinking that a bag that sits in the sun for a long time will eventually break down from UV exposure, etc. Comments or thoughts? Thanks!
