Kona Front Cup Holder Expander

Fits like a glove - also love that it secures the larger drinks but its also low profile so it's not overwhelming the aesthetics of the car.

They work great. Fit within the existing cup holders and allow my Hydroflask to be used. I did find out that older Hydroflasks might be a little bit wider and this fits that as well, so you might have just a little wiggle room on the newer 40oz hydroflask bottles.
