A drink while running or hiking shouldn't drench your clothes or slow you down, so Hydro Flash made the Narrow Mouth Sports Cap to fit your 18oz or 24oz narrow-mouth bottles.
Hydro Flask Narrow Mouth Sports CapOur narrow mouth sports caps were designed with the mover and shaker in mind. The convenient pop top makes drinking on the go a piece of cake. We spent some serious time creating a sports top that fits your needs, the flow is great and the attachment loop makes it easy to clip your Hydro Flask to just about anything! The narrow mouth sports cap fits our 18oz. and 24oz. narrow mouth bottles.Our Sports Caps are made from polypropylene, which means they are BPA-Free.
