David Miller
Took FiltSipy on a 4-day trek across the Rockies. Sipped right out of mountain creeks and the water tasted crystal clear. Fits on my squeeze bottle perfectly!

Incredibly light and easy to pack. We keep one in each car glove compartment and our bug-out bags. The Buy 1 Get 1 deal made it an absolute no-brainer purchase.

Solid build quality and impressive water flow rate. Far easier to draw water through than other filter straws I've used. A mandatory piece of gear for any wilderness trip.
