Being prepared is never a bad thing, especially when it comes to refreshing hydration. Grab an extra lid and rest easy knowing it’s insulated like every other Hydro Flask product, so you can always keep your contents at the optimal temperature.
Please note that the Wide Mouth Flat Cap does not fit on the older style Wide Mouth flasks. To find out whether this lid will fit your bottle, check the Wide Mouth Fit Guide
