With its smooth, graceful curves, the Wide Loop Cap is both elegant and functional. Designed with the athlete and the multitasker in mind, the attachment loop makes it easy to clip your Klean Kanteen® onto a belt, harness, pack or anywhere else you need easy access to your drink.
The Loop Cap is designed to fit the universal, external thread design on the wide-mouth bottles. While the outside of the cap is BPA-free polypropylene (pp#5), the inside is 100% food-grade, 18/8 stainless steel, which creates a totally stainless interior inside the bottle.
