I use it for a 70m 9.8mm rope and I really have to crank hard on the brim when i'm rolling it closed. The closing system wasn't obvious and took a few tries to figure out. It's a little awkward to carry, but that's probably because I'm using a really heavy rope and filling the bag to capacity. The material is really solid and the inner tarp has plenty of space for the 70m rope. The closing strap, which has to wrap around the bottom of the bag to keep the brim folded and the bag closed, can sometimes slide off of the bottom and cause the bag to basically open, either dumping your rope, choking you, or throwing you off balance. If you cinch it down properly, this won't be an issue but it takes a few tries to figure out.
