A hikers friend of mine turned me on to this product the other day. Its a 25' and 60' spools of kevlar tread/string (yellow) and 50' spools of Technora (Black) in a "quick deploy" compact spool. The guy selling them in small business out of his home, was marketing it to survivalist on a Zombie internet forum of all places At first I didn't get it then it hit me like a ton of bricks. That would be perfect for a bear bag. pull out a length, tie off the spool so more does not unravel, and CHUCK the spool over the tree limb. You don't need a stick to do a PCT hang, just use the spool. I ordered 2.
