What is better than a sweet and creamy Ice Cream Sandwich while out backpacking or hiking? They are lightweight, portable, great tasting freeze-dried ice creams, individually packaged, for your enjoyment. A super moral booster on a hard trail or rainy day. While out hiking or backpacking grab an Astro Freeze-dried Ice Cream Sandwich for a quick snack. No preparation required. We take the cold out so it won't melt. A favorite of kids and adults alike. Vegetarian.
