The M8 Canteen is a water vessel that has capability while blending in. Its designed to carry daily as part of your EDC without looking out of place in urban environments (like office, gym, etc.) but just as capable in the great outdoors. In extremis it can be used to boil water in a survival situation to disinfect (understand this will harm the coating and should only be done in a survival situation). We chose muted colors that can blend-in with various terrains. The rear of the bottle features a survival signal diagram to aid your memory for creating ground-to-air signals.
