Klean Kanteen Sippy Adapter (does NOT include Spouts)
Many accessories are available for Klean Kanteens. All caps and lids are interchangable with all sizes of Klean Kanteens and we only use non-leaching Polypropylene #5 (PP#5) in our caps and lids. Both the loop and flat caps have stainless steel bases to prevent plastic from coming in contact with your beverage.   Note: The Sippy spout is not included with the adapter cap.
