Klean Kanteen Plastic Loop Caps are a leak free solution to transporting liquids without spills.

These caps are manufactured from BPA and toxin free polypropylene, with a large silicon washer for water tightness. A handy attachment loop enables the cap to be lashed to your backpack for instant storage.

The leak proof thread fits all Klean Kanteen Classic bottles (44mm diameter) and is dishwasher safe for ease of cleaning and sterilising.
