Shape Shifting Unlike other hydration reservoirs the Shape Shift can completely change its size. When full the Shape Shift holds up to 3 litres of fluid. When you have used some of the fluid, or when you are packing light, the reservoir’s baffle can lock for a slimmer profile. Once locked the Shape Shift can hold up to 2.5 litres and the locked shape creates a slim profile with an increased level of stabilisation which is perfect for when you are wanting to move at a faster pace. Robust Design The Shape Shift has been designed to feature an extremely durable construction so that it can keep you hydrated even on your hardiest of journeys. The reservoir is therefore made from abrasion resistant TPU and RF and comes with welded seams. This offers a huge level of durability and elasticity. Refilling The Shape Shift comes with a large opening at the top. This makes filling and refilling the reservoir easier than ever. The opening comes with a slide seal that securely fastens the water inside the reservoir and has been specially designed to ensure that there is no spillage or wastage. The Shape Shift also comes with a Plug-N-Play design within its connect system that lets you disconnect the drink tube, which comes with an auto-shutoff valve to prevent leaking, and remove the reservoir from your pack without having to re-tube the entirety of your pack. Cleaning One of the best things about the Shape Shift is that it is so user friendly and has been built for quick on the go use. One aspect to help you when you’re out on the field is that the reservoir can fully reverse in on itself to ensure that you can fully, and accurately, clean the entirety of the inside of the vessel. This means that you can clean the device to its very core stopping a build-up of potential bacteria.
