Sand bag.

When you’re off to the seaside (or wherever the road takes you), forego the armload of totes and just bung everything in this giant carry-all. Towels, snacks, books, and, of course, a sun hat with a wide circumference—there’s room for everyone and then some. It’s made of sturdy silicone so even if you spill something inside, it’ll wipe right up. We’re especially partial to that plucky tangerine shade but go for grey if you’re looking for versatility.
