HydraPak has taken the humble soft flask and turned it into a backcountry essential. The PackFlask+ is a 750‑ml collapsible bottle equipped with an integrated filter that removes bacteria and protozoa—so hikers can scoop from mountain streams without worrying about Giardia or E. coli. The high‑flow nozzle self‑seals to prevent leaks, and the filter screws onto the flask, meaning it can double as a squeeze filter when used with other containers.

Weighing only 116 grams when empty, the flask packs down into a stretch mesh pouch and attaches to a backpack strap via a clip, keeping hands free. Its removable cap sports a wide opening for fast fills and an integrated dust cover to keep the mouthpiece clean. Materials are BPA and PVC‑free TPU with RF‑welded seams for durability. HydraPak rates the filter for up to 1,500 liters at a flow rate of more than a liter per minute—plenty for an entire thru‑hike season.

For anyone serious about fast‑and‑light travel, the PackFlask+ is an elegant solution that eliminates separate filters and bulky bottles. The flask is available now on HydraPak’s official site.
