The Hydro Flask Insulated Tote Food-Cooling Bags give you enough space for a family picnic or a weekend away. Part of the same series that includes the lunch bag, these insulated totes come in 20- and 35-liter capacities. If you’re headed out for an afternoon at the beach, take your insulated bag with you to keep your food and drink cool for at least four hours. Food safety is important for you and your family to stay healthy. And these insulated coolers help ensure your food stays the right temperature. But these food storage bags can also be used for drinks. So you can hit up the store and then bike to your friend’s party without the beer warming up.
