Mine is grey with a purple stripe...it's this one. Hubby just brought it home for me as I was complaining about not having a bag I could wear messenger style.

I use it as a purse and on the bike. The one I linked to is small enough to function as a purse but big enough to have some room for extras -- you could carry a book or a small lunch. I usually have a sippy cup for the kiddo and other toddler supplies stashed.
