Took this on a three-day backpacking trip and it made hanging my bear bag so much faster than fiddling with a knot around a rock. The sack holds the rock snug and I can just clip my line and toss. Wish I'd bought one years ago.

Stuffed my 50 feet of paracord in here after a trip and it swallowed the whole coil with room to spare. The sack itself is thicker than the flimsy one I had before, so I'm not worried about it ripping on branches.

Tossed this over a high branch on my first try, no fumbling with knots or re-throws. The fabric feels tough enough to handle scrapes against bark, and it's been doubling as a tidy cord keeper in my pack since.
