The GravityWorls 2.0L System - Bottle Kit allows you to filter 2 litres of water without pumping, straight into your water bottle or hydration reservoir.
The minimalist GravityWorks 2.0L Bottle Kit system is both ultralight and ultracompact, thanks to a simple adapter that easily connects the pump-free water filter system directly to a water bottle or hydration reservoir, conveniently filtering water for 1-4 people in the backcountry.
Gravity fed water filtration systems are quite new - this one is very light indeed - so its ideal for camp use. On the downside filters can get clogged - and this one will be no different - if you expect to take water from sources without sediment then this would be a good choice to filter out the nasties heavily contaminated water will clog it quickly though and it would only work excruciatingly slowly!
There are a couple of versions of the Gravityworks now, the original had two hanging reservoirs, this one has one to hang somewhere with the clean side reservoir being a bottle - this format is easier to use once its full of clean water. Both the dirty reservoir and the bottle receptacle are 2.0L.
The kit also includes a universal bottle adaptor. If you prefer to use a rigid bottle for your drinking water then the adaptor allows you to filter straight into it rather than the platy bottle that comes with the kit.
