Heavy Bags

Sooooo, after much feedback and testing, the Superpac has some new updated features.  

1. The seat rail strap, which previously wrapped over the outer pockets, now wraps under them.
2. 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.
