Any material dislodged falls straight down into your bag." I've been using the Platypus system for four years now and much prefer to leave the "dirty water" bag open.  I backflush and dump regularly, so anything that might drop into the bag gets tossed.  But I do seal the "clean water" bag and leave it that way, specifically to keep debris out.

Your right. My natural inclination is to leave the bag open as well as I find it annoying to try and seal it.  Although I must admit to  becoming annoyed having debris fall in no matter how careful I try and be......I have also had bugs fall in. What might be slick is a "hanger system" where one avoids having to employ a limb in the first place. It would have to be quick, easy and weightless and be able to stash itself in the stuff sack the platypus resides in. Just a thought. No more looking for the right branch.............Just slap it around a trunk with its little arm and it is always the right height with no bark falling in. Gonna have to kick that around some...........Or maybe just a cloth type cover laid over the top? Or maybe just don't worry about it  ;D
