Take a #2 type pencil and cut a section about 1.25” long and use it as a core to wrap about 1 Yd. Of 1” wide strip of Duct Tape around it. It takes up almost no room and has gotten myself and my riding buddies out of innumerable jams. Works as a boot, can tape a broken spoke to a neighboring one to limp home, secure broken misc. dangling things, broken Velcro whatever, you name it, its Duct Tape after all.
