Klean Kanteen Flip Seal Sports Cap - 100% Leakproof | Black

Compatible with all new and old Klean Kanteen classic threaded bottles!

The new ergonomic design Flip Seal Sports Cap offers 100% leakproof protection and features a removable stainless steel straw - sip with the bottle upright with the straw in place, or tip to drink without the straw. The Flip Seal Sports Cap is compatible with Klean Kanteen Classic narrow mouth bottles (with internal threads).

This improved design is easy to flip open and shuts securely to form a leakproof seal, ideal for children and adults with reduced hand strength. The wide spout opening is comfortable to drink from and provides a steady flow rate. Inside the lid is a removable telescopic 90% recycled stainless steel straw, so it easily adapts to any size bottle from the Classic narrow mouth bottle range (12oz, 18oz & 27oz) - just what you need in a busy household with multiple Klean Kanteens!

With an easy-to-carry attachment loop to carry your bottle or clip to your rucksack, this 100% leakproof design can cope with school bags and buggy trips without soggy accidents. Super durable and dishwasher safe, providing simple hydration on the go with no fuss and no spills.
