Mainstay is the only emergency food developed specifically for both land-based and marine use. Mainstay meals are specially prepared in Survivor Industries own bakery under strict supervision to ensure freshness and quality. Each pre-packaged meal provides a nutritional balance of vitamins and minerals. MainstayTM has emerged as a food product unlike any other. Before it came into the picture, emergency food bars were only being made for short-term use. Survivor Industries changed all that when it created a great-tasting, non-thirst provoking product with an extraordinary five-year shelf life. MainstayTM is specially formulated for land-based high stress situations. Each package contains 9 pre-measured 400 calorie meals, which allows a person to get their full nutrition in a challenging situation.
