Hydrapak Ultraflask+ Filter 500ml
Vest compatible filtration.
Lighten your load and drink right from the source. Hydrapak took their go-to flask and added filtration to create a system that delivers hydration without contamination. The filter-light and compact-screws on top so you can drink right from the flask. Or-if you’re carrying more water-use the system to fill a bottle or reservoir. Effectively removes common waterborne bacteria, such as E.coli (99.999%) and parasitic cysts (99.9999%) per HSF 42.
