You need a good backpack to carry all of your stuff. It has to fit well, carry your items safe & securely, and it has to look cool. The Adidas Y-3 fulfills all of these characteristics. It is a really great looking bag. The low-profile design limits what can be carried, but it usually goes that-the bigger bag, the more stuff you tend to put inside it. The Y-3 limits you to carrying all but the bare necessities. It has some pretty nifty carry options and also features Adidas Patented ClimaCool Technology. Adidas is SOLD OUT, but if you look hard, they're still out there. This stylishly small ninja-styled pack goes for $410+ at the Adidas store.
