This thermal-insulated tote is my ideal picnic basket and market tote. It keeps food cool and fresh for hours, then folds completely flat for storage in small spaces when not in use. Unlike more traditional picnic and market baskets, whose weight alone can weigh my arms down, this basket weighs next to nothing (and has a nice cushioned handle!) so all I'm hefting is the food inside. I've been using it all summer to tote my picnic fare around the city, to keep my delicate produce protected when I go to the market on the hottest days, and to pack in my car, full of perishables and ice packs, for the long haul to the lake house.
