CNOC Vecto Collapsible Bottle 2L 42mm

The CNOC Vecto 2L is a collapsible TPU soft flask holding 2 litres at just 87 g, built with two separate openings: a wide mouth at the top for fast scooping from a stream or puddle, and a 42 mm threaded neck for attaching a filter. That dual-opening layout means you can dip and fill quickly from shallow water sources that would be awkward to fill through a narrow filter thread alone. The 42 mm neck is compatible with Katadyn filters, so the Vecto can serve as the dirty-water reservoir in a gravity or squeeze filtering setup. It packs flat when empty and the food-grade, BPA/BPS-free TPU handles being folded repeatedly without cracking. At 2 litres it is meant for camp water storage and filtering rather than as a bottle you drink from on the move - carrying it full adds real weight, so most hikers fill it at camp or a water source rather than hauling 2 litres all day.
