Took this on a three-day hike across the Lake District. Drank straight from mountain streams without any stomach issues. Crystal clear taste and remarkably easy to use!

Incredible kit for wild camping. Screws right onto my standard water bottles and weighs practically nothing in my rucksack. The Buy 1 Get 1 Free deal was amazing value.

Essential survival gear. I keep one in my car and one in my bushcraft pack. Fast flow rate compared to other filter straws I have tested over the years. Highly recommended!
