An evolution of the double sided rope bag

I'm aware this has been looked at and covered in previous products but I think I have found a new form factor for the double ended rope bag. 

The double ended dry bag is pretty much perfect for it, it folds up into nothing use of plastic stiffeners give you a nice opening that stays open.

This example isn't as burly as I'd like, lacks the stiffening plastic strips on both sides, and is a bit small. But it's a good start. I've played around with it at home and it does a good job. I hope to make an improved prototype soon. 

Wouldn’t its 20L contain a 60m rope?

It can, but 25L would be better.
