We have a bag that I think is similar to the Sherpani bags. It is from target and made by Swiss Gear. We ♥ it!! It isn't girly so my husband will carry it, and it holds a lot more than you'd think. Here is a link to it and it can be found in the Target stores.

Nice little bag, with lots of pockets and a padded section that fits an iPad nicely.
