Easier to tote than plastic or metal lunch boxes, and designed to keep food fresher, too, our reusable lunch bags let you send your child to school with a healthy homemade meal. Pretty butterflies and contrast trim brighten our retro and classic designs. Shell is woven of tough 600-denier polyester with a moisture-resistant coating inside. Interior lining is made of PEVA, an environmentally friendly, food-safe vinyl that's made without chlorine or plasticizers. The Classic lunch bag features a molded interior so it's easy to clean. Designed to fit our Hot/Cold Food Storage Container and our Spencer Food Storage (both sold separately). Straps on the back of each lunch bag allow it to piggyback on our Mackenzie Small, Large and Rolling Backpacks (sold separately). Personalization is available for an additional $7.00.
