This Camelbak Squadbak 25 Litre Hydration System is a huge water pack, that reduced the need for a jerry can in the field. The Squadbak allows you to easily carry large amounts of water, to be used for refilling water bottles or smaller Camelbak systems and when empty can be stored flat, taking up much less space than a traditional jerry can. 

The large diameter hose, can be used with two HydroLink connection points to quickly backfill the hydration pack, or used to to refill any other water container. The Squadbak holds a 25 litre Beast Water Reservoir with Hydroguard, helping prevent the growth of bacteria in the pack. 

These are in Grade 1 condition, showing signs of use but still in good working condition.
