Nothing special, just mod'd a bishop bag.
I got a Seatosummit XXS(2.5L) Ultra-sil stuff sack for my ENO DN. I decided to leave the attached stuff sack attached so I had another spot to stash things besides a ridgeline bag.
I made a hole by heating up a 1/4 nutdriver(3/8 in diameter) and melting the bottom of the bag. I added a 3/8 grommet to it

It was tight squeezing the rope through, but it worked.
