On the clean side, select between the DrinkCap for drinking and pouring and the ConnectCap™ that attaches to narrow-mouth bottles. The system is built to be safe, effortless and long-lasting. Two cleaning methods—shake-to-clean and backflushing—keep the filter flowing fast throughout your trip, while the Integrity Check process allows you to ensure it’s still safely filtering water. With its incredible ease-of-use, packability, and fast-flowing performance, the QuickDraw 1L Filter System is the best squeeze filter for your backpacking trips.
