Pump-Free Gravity Flow & Effortless Hands-Free Hanging
Never waste physical energy after a gruelling day on the fells. GraviPuru utilises natural gravitational pressure to draw water smoothly through the filtration core, allowing you to fill pots, hydration bladders, and canteens without touching a pump.
- Suspends securely from tree limbs, tent poles, or shepherd hooks with the integrated hanging strap
- Hands-free operation lets you pitch your tent or prepare camp meals while your water purifies
- Requires zero manual pumping, electrical cords, or spare replacement batteries
Multi-Layer Filtration Core for Sediment & Odour Removal
Enjoy crisp, pristine water from any freshwater brook, tarn, or loch. GraviPuru incorporates an advanced multi-layer filtration system designed to trap suspended silt, clear turbidity, eliminate swampy smells, and target common waterborne impurities.
- Effectively screens out grit, mud, organic debris, and microscopic suspended matter
- Significantly reduces musty odours and stale organic tastes for crisp, refreshing hydration
- High-throughput flow provides rapid filtration without frustratingly slow drips
Generous 3.78L Reservoir & Wide-Mouth Quick Fill
Supply your whole hiking party with plenty of drinking water in one single trip to the stream. Built with a roomy 1-gallon (3.78-litre) capacity and an extra-wide opening, refilling from shallow brooks or campground standpipes is effortless.
- Ample 3.78L capacity caters to cooking, brew rounds, and trail refills for solo or group trips
- Wide-mouth design scoops water swiftly even from very shallow streams and low tarns
- Quick-seal closure ensures zero spills or leaks when carrying back to your basecamp
Food-Grade TPU Reservoir & Ultra-Packable Roll-Up Design
Constructed to withstand unforgiving outdoor conditions without adding dead weight to your kit. The food-grade TPU bladder remains puncture-resistant and supple in cold temperatures, rolling down to the size of a water bottle when empty.
- Tough abrasion-resistant TPU handles rough rocks, sharp heather, and pack compression
- Flexible kink-resistant silicone delivery hose provides targeted filling into bottles or cookware
- Roll-up collapsible format saves vital pack space and weighs a fraction of bulky rigid pumps

"Used this on a three-day wild camping trek in the Lake District. We hung the 3.78L reservoir from a rowan branch by the tarn, and by the time we had pitched the tent, we had clean, crystal-clear water ready for evening tea. Completely eliminated the aching arms of pumping!"
"The multi-layer filter works genuine magic on murky Scottish burn water. No peat taste, zero cloudy grit, and the TPU bag rolls up small enough to tuck into the outer mesh pouch of my rucksack."
"Bought this for our Peak District family hikes and emergency kit. Filling 3.78 litres at once saves multiple trips down to the river. The food-grade TPU feels extremely tough and doesn't impart any rubbery taste at all."
