Banshee Bungee Urban Assault Bungee - 10 Foot Package - $104.96

For shorter drop-ins and quick escapes, the Banshee Urban Assault Bungee helps you get on that rail in a fraction of the time it takes to build a ramp. At just six pounds and ten feet unstretched, it'll tuck into a pack or big jacket pocket easily. When stretched, it'll launch you at up to 20mph into whatever feature you find, then tear down before Johnny Law can show up. - $104.96
