PackFlask™ 750ml

$29.7 ~~$45~~ In stock

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.

Steven ★★★★★ Oct 18, 2026

Took it on a three-day trek and the way it clips onto my pack harness means I barely notice it's there. The 750ml capacity is perfect for topping off at streams without hauling a heavy bladder. Honestly, the ultra-light build makes me wonder why I ever carried a bottle in my hand.

Amelia ★★★★★ Oct 14, 2026

Didn't think 750ml would feel this light on a long trek, but it basically disappears once you strap it to the harness. The bite valve flows fast without leaking in my pack, and refilling mid-trail takes seconds.

Clipped this to my harness for a 12-mile ridge day and barely noticed the weight. The bite valve flows fast without leaking, and refilling mid-trail took seconds. Exactly what I wanted for fast-and-light hikes.
