More fun, less sand.

Shake your troubles away

Flip the bottom flap to reveal mesh netting that keeps your beach swag in while you shake unwanted sand out.

Beachy keen materials

Its coated canvas repels water, roomy interiors have inner and outer pockets, and cotton straps feel soft on skin but don’t slip off your shoulder.

More fun, less sand.
More fun, less sand.

Attention, kiddos:

No more sandy pretzels, PB&Js, or complaints. Leave the sand castle on the beach, so you can enjoy a comfy car ride home.

Invented By


New York

Like all Quirky products, Shake was invented and influenced by real people like you. Avid summer surfers Charlie Dougiello and Spike Mendelsohn spend a lot of time at the beach, waging a constant war against sand in their stuff. To solve this problem once and for all, they co-designed a waterproof, mesh-bottom bag—and submitted it to Quirky. They still spend plenty of time in the sand, but bring a lot less of it home with them now.
