reviews
"This is a good day hiking filter, where you’ll just be filling it and drinking (only very light suction is needed to pull water through the filter. "
"I bought this because I don’t always have access to the best water. That being said this filter is fantastic, most of the time all I can taste is cold there is no flavour or smell to the water."
