I really like the new Mariposa. However, one thing I have found is that the shock cord that closes the roll-over lid keeps getting in the way when packing. Yesterday, I had a eureka moment, when I realised that a small karabiner could do the job just as effectively but get rid of the tangle of shock cord.

It’s really quick and easy to use and much neater. The grosgrain loops are large enough to thread the opened end of the karabiner through easily.
