Roswheel riding saddle bag

If you're a racing snake, you might argue that riding saddle bag contents can be made into a neat package, slotted into your middle pocket. You'll also argue that a tube should not be in the saddle bag, as it will get chafed and punctured over time. This is true, but for some people, fitting small packages into pockets isn't an option. Skinny people with loose tops keep having to adjust their clothing, while most other riders require pockets for other things, like food and a phone.
