Great storage, a bit bulky
The storage space is fantastic and I love the organization pockets. It’s a little bulky on my small bike, but the quality and ease of use make up for it.

Solid bag with excellent features
This bag is very well made and the weather resistance is a big plus. The only downside is that you need the Topeak rack for it to fit, but once mounted it’s rock solid.
