Thread: Grayl - water bottle filter

I also use the hydrapak inline filter and the Stow 1L bottle. Its handy because I can use it to filter water into my 3L hydrapak bladder. Using the filter with the bladder is a pain in my opinion as the filter limits the flow. With the Stow bottle I can use it for filtering into the bladder to keep the bladder clean, or i can drink straight from it.

I originally looked at the Grayl, but they are comparatively very heavy and offer reduced water carrying capacity. They also take up a lot of room. The flexible nature of the Hydrapak 3L bladder and the stow bottle mean you can make them very compact when not in use, and the plug and play nature of the filter system is very handy and versatile.

Hope this helps
