Timbuk2 bags are very trendy where I live. All my friends who ride around town on their old ten-speed bicycles or fixed gears have a messenger bag from this company. So I thought, why not? & I got one too- peer pressure. Anyway, I really like this bag. I don't use it for riding around much, because this "Special Edition Retro Bag" is pretty big and it makes it more difficult to balance on a bike. But I do use it to tote around textbooks & notebooks at school & for this, it is perfect. It has a lot of space so I can fit almost all of my school materials in it without having to make multiple trips to my locker throughout the day. It also has a few inside pockets in which I usually store the smaller things- iPod, cellphone, etc. The shoulder strap is very comfortable & doesn't hurt my shoulder even though my bag is usually filled with pretty heavy things. This classic bag doesn't feature the waterproof wax lining that comes in the newer bags, but that doesn't really matter too much to me. It's all nylon... & blue.
