This mid-sized neoprene tote is the gold standard among reusable insulated lunch bags. Keeps food cold (or warm) for up to 4 hours, depending on the outside temperature. The flat bottom keeps it upright, perfect for bottles or dishes that you don't want tipping over. Soft-grip handles make it easy to carry. Machine-washable so there's no need to worry about spills. Stores flat, but expands to fit a variety of containers. The zip closure keeps it secure.
