CNOC Vecto 3L 42mm Reservoir Blue

CNOC Vecto 3L Reservoir

A lightweight, dual-opening water reservoir built for collecting, storing, and filtering backcountry water with your filter of choice. The Vecto's wide opening fills in a couple of scoops, its standard screw neck connects directly to most popular squeeze filters, and its 3.2-ounce weight makes it one of the lightest high-capacity dirty water bags available.

Why We Carry It
It's the reservoir we recommend for gravity filter setups and thru-hikers who want a durable, easy-filling dirty water bag that pairs directly with the Sawyer Squeeze or Katadyn BeFree without adapters.

Highlights

• Dual opening design — A wide slider-sealed opening for fast, easy filling with a couple of scoops from any water source and a standard screw neck for direct filter attachment without a separate hose or adapter.
• Available in 28mm and 42mm thread sizes — The 28mm version connects directly to Sawyer Squeeze, Mini, Micro, LifeStraw Flex, and HydroBlu Versa Flow filters. The 42mm version connects to the Katadyn BeFree. Choose the right thread size for your existing filter system.
• 3L capacity at 3.2 ounces — Serious dirty water storage at a negligible weight. Carry enough water for a dry camp or a long waterless stretch without adding meaningful weight to a minimalist kit.
• 220-pound breaking point — A durable TPU construction that handles the stress of squeezing, hanging, and field use without tearing despite the soft, packable material.
• FDA approved BPA, BPS, and BPF free TPU — A 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 air drying without the trapped moisture problems of narrow-mouth reservoirs that develop mold on extended trips.
• Packs flat when empty — Collapses to a compact, packable size for stowing in a pack when not in use on dry sections of trail.

Best for

Thru-hikers, backpackers, and gravity filter users who want a lightweight, durable dirty water reservoir that fills fast and connects directly to popular squeeze and gravity filter systems without adapters. A strong companion piece to the Sawyer Squeeze or Katadyn BeFree for a complete, ultralight water collection and filtration setup.
