Geigerrig RIG 700 Hydration Pack

The Geigerrig RIG 700 hydration pack is vital for your outside treks. Not only because it’s a hydration pack, but because it uses a rubber squeeze pump to add pressure inside the pack. This allows you to spray the water into your mouth, rather than use vital energy to suck it out. Double bonus is that you can use it to spray your head to cool down too. Why didn’t someone think of this before?
