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 smartwaterA(R) and most Platy bottles. On the clean side, select between the DrinkCap for drinking and pouring and the ConnectCap(TM) 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. Customize your system with this fast multi-compatible, ultralight squeeze filter. Combine & Customize: I/O dual threads and the ConnectCap(TM) let you dial in your custom leak-free system using the clean and dirty vessels you prefer, like smartwaterA(R) bottles and Platy bottles.
