Klean Kanteen Classic Sport Cap
Best leakproof hydration solution for active kids and busy commuters.
This cap finally solves the leak-prone nature of most sport lids, offering a truly secure seal for your narrow-mouth bottles. The one-handed flip mechanism is satisfyingly snappy, though you sacrifice the convenience of an integrated straw for that rugged, spill-proof reliability.
