From the manufacturer

Improve your backcountry filtering experience with the do-it-all QuickDraw Filter. Hollow fiber technology allows the QuickDraw to filter water fast (3L/m) while remaining compact and ultralight (2.4 oz). It’s designed to work seamlessly with a wide range of bottles and reservoirs, empowering you to assemble a filter system tailored to your preferences. The dirty side I/O (inner/outer) threads attach to QuickDraw reservoirs as well as common narrow-mouth bottles like smartwater® and most Platy bottles. On the clean side, select between the DrinkCap for drinking and pouring and the ConnectCap™ that attaches to narrow-mouth bottles. The filter 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. So, choose your color, pick your vessels, and head out with a fast, effective and super-easy water filter system that’s all yours.
