I love that the waist strap is adjustable and has a band to keep it secure. Also it matches my summer outfits and let's never travel hands free with my 5 year old. This bag holds 2 of my phones my wallet extra money, important papers and some makeup (lipstick, mirror, mascara) there is three compartments and I recently took to to a rave and a sprinkler park. I put my keys, money and phone wrapped in a hand towel in the inner sanctum compartment if the bag. All were dry and I got soaked at the sprinkler park. Great buy! My fav bag. Very futuristic looking and I get alot of compliments and gawks. I am happy I will order another color soon. I'm very excited.
