Our stroller bag is designed to fit any puchchair and fits ALL THE NECESSARY items a mama might need on a day out with the baby. It has two inner bottle slots, two outer bottle slots, an invisible pocket on the inner side for phone, and also a large pocket with zipper on the front where you can safely put your wallet and keys. 

But because we sell it with a shoulder strap it also doubles up as a regular bag that you can use in any non baby related situation. We do it all the time - it's perfect.
