Klean Kanteen Wide Flip D-Ring Cap
The Flip D-Ring cap is a sturdy plastic outer with easy to clean 18/8 stainless steel interior cap (the same material the water bottle is made from) so your drink never touches plastic.
The leak proof Flip D-Ring Cap features (you guessed it) a stury metal D-Ring which folds flat for a great low profile and won't leak as you carry about your day-to-day.
Compatible with wide neck Klean Kanteen bottle only.
Dishwasher safe, this excellent cap is guarenteed to withstand life's thrills and spills.
