BTW was the Coleman trail foods actually a freeze dried product as the shelf life seems quite limited for such as expensive product. A freeze dried product should have a 5 year shelf life such as with the Mountain House range.
Does anyone have a source for these type of food grade resealable strip Mylar packaging baggies that the freeze dried food manufacturers use. They would be really useful to home vacuum seal individual portions as 500gm portions (5 days use) although useful for multiday hikes are a little large to carry for 1-2 days
