CNOC Tethered Cap 28mm

The CNOC Tethered Cap 28mm is a replacement screw cap with a built-in loop ring so it can be clipped or tied to a bottle instead of getting lost when you unscrew it on the trail. It fits the standard 28 mm PCO thread found on most PET soda and water bottles as well as CNOC's own bottles and bags with the same neck size. This is a small, single-purpose accessory - useful if you have lost the original cap on a bottle you already own, or want a spare that will not disappear into a stream, rather than a product with any features to weigh up beyond fit and the tether.
