Diving into a cavernous duffel bag for your last clean pair of clean hiking socks can be extremely annoying, which is why you need the Patagonia Medium Black Hole Cube to facilitate easy access to must-have items when you're traveling on the road or flying to your favorite destination. Zippered mesh partitions separate your favorite stuff, hygienic accessories, and sports equipment, such as fishing gear and ski equipment. Polyester ripstop fabric withstands regular use and abuse, especially when it's subjected to overzealous airline attendants and cram-packed vehicle trunks. Plus, there's a TPU laminate and DWR finish that prevents outside moisture from ruining sensitive items.
