The Urban HardPack is on of the most fashionable bags I have seen to date, I really mean that, this bag is smooth as silk. The Urban HardPack is one of the few bags which achieves the much sought after combination of functionality and style. The HardPacks solid outer layer is sleek and shiny enough where you can see your reflection, at the same time it provides unsurpassed protection for whatever you are carrying. I mean this thing is solid. Its internal and external enhancements accommodate today's high tech Mac users. The HardPack has compartments with zippered pockets, a key ring clip and straps for securing personal belongings. Since the HardPack uses straps to secure your items, it accommodates most sizes of laptops, MP3 players, cell phones, PDAs, and anything else the Mac user on the go needs to have. I would not however recommend this bag for any type of extreme sports, BMX, skateboarding, etc. Although this bag is very durable, and provides incredible protection for whatever is inside of it, the shiny front scratches very easily. Take one spill with this bag and you wont like the way it looks. On the upside, Axio also makes quality soft front bags, for our more extreme users. The Urban HardPack is $149.95 and can only be ordered at http://www.axio-usa.com even of you are not interested in guying a bag I encourage you to visit their flash site, its really something else ( in a good way )
