This bag is huge. No joke.
This bag is giant. Exactly what I was hoping for. Roomy enough to lay folded towels flat at the bottom, all your swim suits and gear. Roomy pockets all around for lotions and sprays. A large zippered pocket for valuables that’s hidden in the seam. Overall the quality is fantastic for the price.

LOVE THIS BAG!
Color: 32l-black, Size: Large
This is an amazing bag for traveling. It folds up easily and took up very little space in my luggage. It made a great multi-purpose tote for our trip. I used it as a beach bag, a grocery bag, and a laundry tote. And when I bought too many souvenirs, I used it as a carry-on to get my goodies home safely. I liked it so much I bought two other sizes.

Best purchase
Color: 32l-black, Size: Large
I was skeptical about this bag before deciding to buy it, but I changed my mind when I got it in hand. The capacity is very big; I can put many things inside when I go shopping. What I like most is the side pocket. It fits my tumbler, which I like to carry around.

Elegant and spacious
Color: Beige and Black With Matching Wallet
What a great purse, spacious and elegant. Sturdy, love the studs on the bottom, so it protects from damage. Colors go with most outfits. Well made and great value.
