CNOC Sport Cap 28mm

The CNOC Sport Cap 28mm is a replacement pull-open sports cap on a standard 28 mm PCO thread, so you can drink one-handed without unscrewing a full cap each time. It fits standard PET bottles, CNOC's own bottles and bags, and Sawyer filters with the same thread size. It is a simple swap-in accessory rather than a bottle in its own right - useful if you want faster access to water on the move than a screw cap allows, or want to replace a lost or damaged cap on gear you already own.
