My favorite rope bag
I've had many different rope bags over the past 12 years and keep coming back to my Superslackers. The rope tarp size is generous, rolling the rope into the burrito style shape is easy, the compression straps on the outside work easily and, contrary to a few others here, I really like the zipper. I will admit I've had the barrel clasps on the end cinches break but they're easily replaced for cheap. And, to be fair, I use this rope bag more than any of my others; multiple times a week.
My climbing pack is an Osprey pack so the elongated shape of this rope bag allows me to strap it vertically to the compression straps common on Osprey packs. This just works really well for me.
I've used this rope bag for 60m x 10.5mm ropes as well as 70m x 9.8mm ropes and never feel like I'm squeezing the ropes in there. The volume of this bag is very good.
