Sooooo, after much feedback and testing, the Superpac has some new updated features.
- The seat rail strap, which previously wrapped over the outer pockets, now wraps under them.
- The seat post attachment point is now adjustable.
Here's the old seat rail strap:
It slides through one of three different loops on the back end of the bag (and was inspired by those velcro straps used to bundle electical/stereo wires together)
The photos have been updated on the Superpac listing with the exception of the non-black versions. However you can rest assured that no matter what color of Superpac you order, it will be of the updated variety.
