The Mountain Vacuum Food System from Stanley is essentially a mess kit on steroids. The vacuum insulated food jar will keep food hot for up to 13 hours or cold up to 11 hours. It’s made from a tough 18/8 stainless steel that won’t rust. The lid is a cup and the insulated jar nests in the cooking pot that includes a convenient handle. To top it off the Mountain Vacuum Food System comes with it’s very own spork so no need to pack along extra utensils.
