Rapid Rope / $35
There are two things you never want to be caught without: A good knife and a stout length of rope. Rapid Rope is 120 feet of 1,110-pound test cord in a tangle-free container slightly larger than a soda can. This means it can be stored nearly anywhere, making it an arm's length or less away. A built-in cutter is also included for one-hand operation.
Weight: 14.5 oz.
