I use this bag on my little Pack cat on rivers down in Mexico. It certainly has seen it fair share of abuse, getting drug on travertine dams and through pokey plants on portage. The bag is soild construction and has lasted much longer than my last rope. Certainly spend some time tossing this bag around the park before hitting the water with it. I also agree with Kelly and jreeder, it's all about the stuff to get the distance.
