CNOC Vecto 3L 28mm

CNOC Vecto 3L 28mm Reservoir

A high-capacity, lightweight dirty water reservoir built for dry camp carries, group filtration, and long waterless stretches where 1L or 2L simply isn't enough. The 3L Vecto delivers serious water collection capacity in a 3.2-ounce package that connects directly to 28mm compatible filters for fast, on-the-spot treatment without an intermediate vessel.

Why We Carry It
It's the dirty water bag we recommend for backpackers tackling long dry stretches, desert routes, and group camping where water capacity matters as much as filter performance.

Highlights

• Dual opening design — A wide slider-sealed opening for fast, easy filling with a couple of scoops from any water source and a 28mm screw neck for direct attachment to compatible squeeze and gravity filters.
• 28mm thread for direct filter compatibility — Connects directly to Sawyer Squeeze, Mini, Micro, LifeStraw Flex, and HydroBlu Versa Flow filters without adapters. Fill, attach, and squeeze or gravity filter clean water directly into your drinking vessels.
• 3L capacity at 3.2 ounces — Maximum dirty water storage in the Vecto lineup for dry camp carries, desert routes, and group water collection in a package that packs to 7 x 2 x 2 inches when empty.
• 220-pound breaking point — A durable TPU construction that handles the stress of squeezing, hanging for gravity filtration, and general field use without tearing despite the soft, packable material.
• FDA approved BPA, BPS, and BPF free TPU — Clean material standard free of common plastic additives across all three bisphenol variants. Safe for long-term water contact without chemical taste concerns.
• Tethered cap and slider — Both closures stay attached to the reservoir so nothing gets lost at the water source or in a dark camp.
• Easy to clean and dry — The wide opening allows thorough rinsing and complete air drying without the trapped moisture problems of narrow-mouth reservoirs that develop mold on extended trips.
• Packs flat when empty — Collapses to a minimal packed size for stowing in a pack when not in use on dry sections of trail.

Best for

Backpackers, desert hikers, and small groups who need maximum dirty water collection capacity for long waterless stretches, dry camp carries, and gravity filter setups where a smaller reservoir requires multiple fills. A strong companion piece to the Sawyer Squeeze for anyone tackling routes where water availability is unpredictable and carrying extra capacity is the safer call.

Compatibility Note

28mm thread fits Sawyer Squeeze, Mini, Micro, LifeStraw Flex, and HydroBlu Versa Flow filters. New reservoirs may have a slight TPU smell from production. Clean and air out before first use. Operational temperatures 20°F to 120°F. Also available in 1L and 2L for lighter capacity needs.
