A 6.7L Lunch Bag, made from Recycled Polyester. Big enough to carry everything you need for the day, including a lunch box, water bottle, fruit, and snacks - the perfect lunch bag for kids or adults. Inspired by dry bags, the roll top and welded lining construction is 100% leak proof (when stored upright). Insulating PEVA inner lining will maintain internal temperature and keep contents cool. Food-safe and water-repellent inner surface is easy to wipe clean. Roll top construction makes it easy to carry, compact or strap to another bag, or bicycle handlebars. Black+Blum are proud members of 1% for the planet and donate one percent of their total annual sales (including this item) to non-profit environmental causes.
