Totes are a type of all-purpose bag with a large center compartment and double-handled, arched straps that can be used to carry a variety of objects. While some bags are simply wide open, others provide a zipper or magnetic snap closure to keep contents secure. Various styles may have one or more interior or exterior compartments for smaller, fragile items like sunglasses or eyeglasses. For work or school, leather models will hold everything from files and books, to a laptop computer and cell phone. Durable fabrics like canvas, nylon and cotton are suitable to take to the beach or on a picnic. An oversized blanket, towel, camera, sunscreen, reading material, snacks and a water bottle will all fit nicely inside. Since taking reusable bags to the supermarket is the modern way to shop, tote bags made from materials like vinyl, that can easily be wiped out, or ultra-sturdy mesh are ideal for trips to the grocery store or warehouse club.
