VectoX

The VectoX builds on Cnoc's familiar dual-opening dirty bag concept by swapping standard TPU for a substantially thicker, reinforced material. Standard squeeze pouches included with popular hollow-fiber filters are notorious for seam blowouts under trail pressure, while paper-thin reservoirs puncture too easily around granite and desert scrub. For thru-hikers and backpackers who rely on squeeze or gravity filtration setups, this container acts as a bombproof collection hub capable of surviving aggressive daily filtering without babying.

Its build centers on a wide-mouth slider opening on one end and a standard threaded neck on the other. Scooping water from trickling seeps or flat, shallow pools takes seconds thanks to the wide mouth, eliminating the frustrating leaf-funneling routine. Once sealed with the tethered slider bar, the vessel holds pressure exceptionally well. Squeezing forcefully against a partially clogged filter will not pop the welded seams, and the material handles abrasion from rough ground far better than standard ultralight bags.

The obvious compromise is packability and weight. The stiffer material does not roll down quite as tight as the standard Vecto, and it carries a modest weight penalty. However, at a negligible price bump over the original, the peace of mind against catastrophic mid-trip water bag failure makes it well worth the few extra grams for anyone heading into remote terrain or abrasive environments.
