Backpacks are ideal for hiking but you have to take them off to get to the contents. Beltpacks can be worn in front or back but have limited storage space and can be clunky riding under a backpack.
The Rotation 180 Travel Away Daypack from MindShift Gear comes with a beltpack that stows neatly into its own integrated cubbyhole at the bottom of the backpack. For easy access to the beltpack, just rotate the whole thing out of its nesting spot to the front of your body. When done, rotate it out of the way back into its backpack slot.
As an added security bonus: The beltpack, stashed in its "room," keeps important documents, electronics, wallets and other valuables safe from prying hands. Both the backpack and beltpack can be worn on their own, and both have multiple internal and external pockets and slots for efficient organizing.
The backpack is 20 inches tall, about 12 inches wide and 7 inches deep, with thick padding on the back and straps. The beltpack is about 10 inches wide by 7 inches high and 2 inches deep and functions as the backpack's stabilizing hip belt when stowed.
An optional rain cover fits over all and comes with an extra rain cover to protect the beltpack when it's out front. The packs come in blue or charcoal.
Cost: $199.99; rain cover is $19.99.
