The lunch version of our best-selling Walrus Cooler features all the same beloved details, including inner mesh pocket for your reusable utensils and an outer pocket for your keys or phone. It's the perfect insulated compact companion for anyone, whether in school, at work, or bringing beers to a friend's house. We don’t recommend placing loose ice directly in the bags. For best results, use reusable ice packs or sealed baggies, as the coolers aren’t designed to hold liquids.
