A true game changer that makes almost any questionable water source safe to drink. The Guardian purifies and filters water, so you don't need to carry chemical water treatment or a UV purifier when you're in virus territory. The gravity system is a low-effort option that needs no pumping - simply fill and raise the reservoir and let gravity filter and purify your water while you set up camp, prep dinner, or just relax.
