"Took the Gravioxy on a four-day wild camping trek in the Lake District. We hung it from a sturdy branch next to our pitch, and within minutes had crystal-clear, sweet-tasting water for our brews and dehydrated meals. Absolutely brilliant piece of kit that saved our backs from carrying heavy bottles."
"Having the 10L capacity is a game changer for family camping holidays in Devon. No more tedious manual pumping or waiting around. It filters stream water quickly and leaves zero plasticky aftertaste. The whole system folds down so small in my rucksack."
"Living in the Scottish Highlands, we keep one of these in our household emergency pantry as well as taking it on hillwalking expeditions. The build quality is superb, the gravity flow is fast, and the 0.01μm membrane gives total peace of mind."
