Make bear bagging easy with this rock sack. Just put a small rock, sand, or gravel in it, tie your bear line (link to 2.0 slick line) to it, and toss it over a branch. Constructed from ultralight but durable 1.43 oz/sqyd Dyneema Composite Fabric to resist abrasion and punctures.

This is also available as part of a Bear Bagging Kit .
