"Took this on a 4-day wild camping trek across the Lake District. We hung it from a sturdy branch by the stream and had over 3.7 litres of crystal-clear water ready for brewing tea and refilling our flasks in no time. Brilliant bit of kit!"

"I used to dread hand-pumping water after a 20-mile hike in the Scottish Highlands. With GraviPuru, you just fill the wide bag, hang it, and let it do all the work while you pitch your tent. The water tastes remarkably fresh with zero river odour."
Callum W.

"Kept one in our home emergency preparedness kit during a recent local water main burst in Yorkshire. It filtered our collected rainwater flawlessly and gave our entire family complete peace of mind. Folds completely flat when stored."
