RuckJack

This waterproof/breathable lightweight jacket comes in two adult-sized models -- one with a rip-stop shell and mesh lining, the other rocking a taslon shell with nylon lining -- that thanks to a few cleverly designed clips and drawstrings, morph into a rucksack when turned upside down, versatility you'll be thankful for when you realize hiking sucks, and you'd rather just be carried around.
