Quick and tiny, the Platypus QuickDraw Microfilter System is our go-to for self-supported ultraruns and ultralight backpacking missions. This compact system rolls up to fit in a hip belt pocket and quickly unfurls when we come upon a water source. The reservoir's wide mouth lets water pour in to max out its 1-liter in seconds, and once the filter is threaded onto the reservoir, we can sip straight from the clean side or squeeze the filtered water directly into our bottle.
