Is this bag big enough for a beach towel and sunscreen?

Yes. At roughly 23 by 14 by 9 inches it fits a towel, sunscreen, a water bottle and a change of clothes with room to spare.

Will sand fall out of the mesh?

The open net weave lets loose sand and water drain through, so the bag stays cleaner than a solid tote. Fine sand can still catch in the knots of the mesh.

Can it be used as a grocery or market bag?

It can, but the wide-open weave lets small items slip through. It works better for bulky items like produce, towels or laundry.

Hand wash with mild soap and cold water, then air dry. Avoid machine drying, which can distort the mesh.

Is $5.80 a good price?

At $5.80 at SHEIN as of November 7, 2026, it is about as cheap as a mesh beach tote gets. Only one store lists it new, so there is little price competition to wait for.
