Like the QuickDraw System but without the reservoir, the easy-to-use QuickDraw Microfilter will revolutionize your adventure filtration system. With its inside/outside (I/O) dual-thread design, the QuickDraw filter cartridge securely adapts to smartwater bottles, most Platy bottles and reservoirs and many common soda/water bottles allowing you to develop your ideal personalized kit. Weighing just 2.2 oz (63 g) and filtering up to 3L per minute, the QuickDraw allows quick and easy access to clean water during ultralight missions and any other adventure. You can either shake-to-clean the hollow fiber filter or perform a tool-free backflush to ensure the fast flow rates will stick around for the duration of your trips. Design elements like the attached clean side cap and grippy-but-not-sticky filter housing eliminate frustrations like leaking water in the pack, lost small parts, and dirt-caked gear so you can confidently go out and explore the wilderness.
