The GEN3 Pathfinder Stainless Steel Widemouth Bottle & Nesting Cup were designed so the bottle will nest inside the cup for convenient and compact storage. Not all containers are created equal, and in a survival situation, unless your container can withstand direct fire for the purposes of boiling/disinfecting water, the effects of water borne pathogens are quickly going to add to your list of troubles. The widemouth design of this bottle allows you to easily obtain water from the shallowest of water pools, which will help conserve precious calories and energy that can be used to aid in your rescue or deal with your survival situation. The Pathfinder Widemouth Bottle was designed to hold exactly 32oz of liquid. Why you ask? The reason is simple. Purification tablets are typically added to 32oz of water, that being the case, you can simply fill your bottle and add the tablets. No more measuring, no more worry. The nesting cup has foldable "bat wing" handles and measurement graduations laser etched on the inside.
