This summer, all of my friends seemed to be acquiring small backpacks that made carrying necessities much easier, and I loved the idea. Purses are not my jam...they're annoying to keep on my shoulder and lug around, but a backpack is small and compact and fits nicely on your back so that you can be hands-free.
I actually have #1 in a bright turquoise rather than a hot pink, and I love it. It's big enough to fit anything I might need, but looks a lot smaller than it is. If you're looking for a bigger backpack, 3,5, and 6 may do the trick. They're not adventure packs so much as they're bags you could use as overnight bags or book bags.
Which do you prefer: backpacks or purses?
