It looks compact but has room for everything including my camera - about 5" x 5" X 5" - I really like the deep side pockets - meant for water bottles I guess, but they held my sunglasses in one and my reading glasses in the other - securely - deep enough not to fall out even when the purse was on the floor by my feet in the airplane or bouncing around during travel.  For security the straps were long enough to swing the purse to my front when walking.  And best of all - when I somehow dumped half a bottle of water inside on the subway (the cap was loose) it did not leak out all over my lap but held the water until I stuffed napkins inside to soak it up about 20 minutes later.  Plus my passport and tickets in the outside zippered up pocket - remained dry.  I had to iron my money though to dry that out.

It is a perfect travel purse and I liked the subdued blackberry color - understated - went OK with black, brown, or gray.
