These are good news here, here's my personal opinion :
I hope there will be an all black version (and enough pcs left when I will pre order it 😅)
About the amount of holes, if ever this is possible, having a transparent material instead would be great. I think I saw another BG from Turkey for the KS18(X)L which has it. If it's never possible, having as many holes as possible while it's still robust enough is great for me
About the zip section, is it possible to have more photos of the above section of the wheel ? When I read you, I understood that the neoprene part you can zip is not attached to the trolley, Am I right ? The zip is a solution, but Whenever there's a problem with it .. How about the use of Velcro and a larger part above the trolley so it can cover it all when folded. And a problem with a Velcro sound less problematic for me.
Just some thoughts coming up through my mind but you're the BG maker and I look forward to knowing more 😁
