The Carhartt Insulated Lunch Box is designed to work with your Carhartt backpack, not compete with it for space. The hook on the top handle clips directly onto any Carhartt backpack strap or handle loop so the lunch cooler rides on the outside of the bag while the full main compartment stays available for books, a laptop, binders, and everything else that fills a school day or a workday. If you prefer it inside, the 8" x 11" x 4" dimensions fit comfortably in any standard backpack main section without taking over. The fully insulated interior keeps food and drinks cold from the morning pack to the lunch bell or the mid-shift break, and the durable lining wipes clean in seconds when something spills inside. An interior zippered mesh pocket keeps a snack, an ice pack, or utensils organized and separate from the main food section. Built from 600-denier polyester with Rain Defender DWR technology, the outside sheds rain on the walk to school, the commute to work, or the hike from the truck to the jobsite. The large zip opening gets you in and out fast and the grab handle makes it easy to pull from anywhere without unpacking your bag. The Carhartt Brown colorway matches the Carhartt Classic Backpack lineup so the two travel together as a complete, coordinated school or work carry system. Carhartt has been building workwear-grade gear since 1889. This lunch cooler is built to the same standard and designed to pair with the backpack that already has your gear.
