CNOC Vecto Collapsible Bottle 3L 42mm

The CNOC Vecto is a 3-litre collapsible water bottle made from TPU, weighing 96 g. Two openings serve different jobs: a wide mouth for scooping from streams or shallow sources, and a 42 mm threaded neck that screws directly onto Katadyn-style filters, so you can fill, filter and drink without transferring water between containers. Empty, it packs flat and takes up almost no space in a pack, which is the point of a soft flask over a rigid bottle — you carry the capacity only when you actually need it, on dry stretches or overnight camps away from water. The TPU is BPA/BPS-free and food-grade certified. At 3 litres it is bulkier than the 1-2 l flasks used for daily sipping; it suits hikers who need to haul a large single water reserve to a dry camp or filter batches at a water source, not fast day hikes where a smaller bottle is easier to handle on the move.
