Fill up, sit back and let gravity give you clean water

Filtering enough water for everything you and your group need at basecamp can take up an extraordinary amount of time and effort. But the guys at Platypus understand that you’d much rather be kicking back and enjoying the camp vibes rather than squeezing endless water through a filter. Enter the nifty high capacity GravityWorks 4.0L water filter, which will keep you and your fellow campers happy and hydrated. This is the perfect filtration system for bigger backpacking groups or for use at basecamp. With a 4L clean water capacity and a filter speed of 1.75 litres of water per minute, you’ll have enough water filtered in a flash for drinking, cooking and washing up. Simply fill the dirty reservoir and hang it up, allowing gravity to do the hard work – with no need to pump or squeeze.

When it comes to doing anything active in the great outdoors, from trail running to backpacking, thirst is one of the biggest enemies. Without adequate hydration to fuel your body, you can’t perform at your best. And not only that – if you’re thirsty, you’re dehydrated. In the worst-case scenarios, that can become a life-threatening problem.

That’s why US brand Platypus made it their mission to offer the finest, adventure-ready hydration and water filtration products on the planet. They’ve now been at it for over 20 years, fine-tuning their designs to develop highly effective, durable and taste-free bottles, bladders and filters. They even have their own certified, world-class water laboratory, which enables them to research, develop and test innovative technologies for a variety of end uses, from town to trail.

It seems that when water geeks, lab technicians, researchers, designers, directors and worker bees come together, with a shared love for outdoor adventure, the result is H2awesome.
