i have the Bullet and since I got it it's all I use, unless I'm carrying a lot, which isn't often. it's the perfect small and light riding pack.

Sag bag. those are hard to get, but i've seen someone with them, and they're amazing

surferbruce---- right on.

I use mine whenever I have a smaller load than the big mess bag, which is often. it is a really great pack and holds more than enough for most of my days (12" Powerbook, D80, couple books, change of shirt or jacket, tools, etc etc)

why, because of the huge billboard logo on the bottom of the bag?

i really like this bag, ive had it for a bit now, and mostly use it for my laptop, but can also fit my rain jacket, lights, notebooks, spare tube, pump, clifbars and other flat small things in it... it fits really tight to your back, and is very comfortable, the pockets are well placed and very large... and in many ways are more useful than the large section... which im not saying is useless, but the biggest benefits are the pockets, which function like jersey pockets and are extremely easy to access. i have 2 very large bags, and ortlieb and a bedlam that i use for courier work, and a small baileys and this bag that i use around town, and for doing dya long riding around across or to the next town where you need to bring a few things, i like this better than any messenger bag... its usefulness is when you wanna ride not too far, and not too heavy... it looks good, feels great etc... im a rapha nut though. it has its place...
