I received the Adventure Medical Kit survival water bottle (Thanks Jeff) and have been using it for a couple weeks. This is a great little product. It is stainless steel with a screw top lid with a loop for attaching a carabineer or securing in some other fashion. The outside is covered with various facts and methods associated with water purification, source location, requirements, etc. Additionally I found that this bottle insulates well and is a convenient size for sticking in a brief case, backpack or just grabbing on go.
