Chelsea bike rack bag

I really like this bag. It's a good size with adequate storage. It attaches very easily yo the back bike rack and is sturdy and well made. The tropical pattern is really cute. It's also portable and can be used for other purposes. Love this bag!

Unfortunately, I purchased this right before it went on sale! Versatile, roomy bag. The tropical print will look great as a bike bag or handbag when I bike in Florida.
