An innovative, ultra-light, efficient system for fast-and-light day hikes and long treks, the PackFlask™ puts hydration right where you want it. Securely attach it to your pack harness for hands-free use. A stretch mesh pouch secures the bottle and — without the flask — carries a phone, snacks, or map. The bottle is light, designed to ride comfortably, and collapses when empty for easy packing. Its leakproof self-sealing nozzle delivers high-flow hydration, and a dust cover keeps it clean. FEATURES INSTANT ACCESS Stretch mesh pouch attaches to your pack harness and securely holds the bottle for hands-free hydration. PACKABLE Sized for easy integration with the pouch, the empty PackFlask™ bottle packs small — just flatten, roll, and stash it away. EASY DRINKING Made for splash-free drinking on the move with a high-flow self-sealing silicone nozzle. DUST COVER Protects the nozzle from dust, mud, and dirty hands. Quickly opens and closes with a single-handed flip. FILTER COMPATIBLE Attach it to most 42mm threaded water filters to create a packable squeeze system. LIGHT AND TOUGH Lighter than traditional bottles, and made of durable TPU with RF-welded seams.
