Love the Aspen Classic Park Pack! It’s perfect for on the go; so far I’ve fit two diapers, a slim pack of wipes, a slim changing pad, my iPhone, my cards, keys and 2 fruit pouches in it for my girls! It’s super cute, fits perfectly as a crossbody (love the thick straps, haven’t tried it as a fanny pack yet), feels really durable and is nicely made. Definitely recommend!
