Their stuff sack can beat up your stuff sack...
Though nominally born of the GORUCK challenge, this combo stuff sack/compression sack from
GORUCK works to seperate items in your luggage or would make a badass carry-on has to be said. $95. This brand is well known for its military grade rucksacks, made in the USA, with a lifetime guarantee and no frippery. Same goes for the
Brick Bag.
