Whirl-Pak's Stand Up bags are ideal for water collection, purification, and storage; and, they are also great for food storage.  

These Whirl-Pak bags are sterile, food-safe, and will not leach harmful chemicals into your water or food supply. They are shipped sealed - you have to remove a perforated tab prior to use. Each bag has a writable area.

These Whirl-Pak bags are ideal for survival kits, because they roll to very compact dimensions, weigh very little, and are incredibly tough.  We include these in a number of our survival kits.

They are safe for use with chlorine tablets, iodine tablets, or UV purification systems.
