UltraFlask+ 500ml Bottle with Filter

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.
