I purchased this drawstring backpack as I make frequent trips to the beach to go swimming or surfing. Thus far I have been very impressed. It was packaged very compactly and appears to fold down easily for storage or travel purposes. It appears significantly higher quality than your regular run-of-the-mill drawstring as the straps are firmly attached and will not untie like regular ones do - further they have buckles for length and comfort adjustment. The size capacity also appears to be very generous - I am easily able to fit a towel as well as other beach items inside without issue. The waterproof compartment at the bottom is excellent, and easily fits my US > 10 size shoes. I'm sure it would make a great use for packing a lunch or picnic items. The zipper straps are also very colorful and of a well-suited color scheme. If I were to lose this bag I would definitely choose to purchase it again, as it has performed its duty well thus far. Will update this review if anything changes but it seems like it will hold up well to usage and the weather!
Fantastic Quality Waterproof Drawstring
