Klean Kanteen Replacment Lids...transform your Stainless Bottles in a flash!
Klean Kanteen replacement caps and lids are interchangable with all sizes of Klean Kanteens and only non-leaching Polypropylene #5 (PP#5) and stainless steel is used in their constuction.
One question we are frequently asked about the Klean Kanteen products is, Why is the sports cap & Sippy Lid made of plastic and not stainless steel? The simple answer is, Your teeth! Polypropylene #5 plastic has been chosen for these lids because it has no known leaching characteristics and is softer if you hit a bump on the trail. This is especially important for baby, and they will appreciate the softer plastic mouth piece, rather than stainless steel against their tiny teeth.
