The team at Cool Hunting definitely puts in the miles when it comes to travel and they're always packed and prepared with the right equipment. They've just come out with a collaboration with Tumi called the Otis, a rugged travel backpack made from a water-repellent coated canvas called Drahar. It's also got endless room for everything you'll need, a TUMI ID Lock pocket for RFID protection, gusseted side pockets for storage expansion, and an add-a-bag sleeve to slip over your luggage handle.
