Water Bottle Suggestions for the Hobie Outback

Does anyone have a water bottle suggestion for the Hobie Outback. I just measured the cup holder and the one left of the seat appears to be 3.75" in diameter, the one on the right is the same but has a 2.5" smaller ring for the base of a cup. A standard plastic water bottle fits in that small ring, but the wider ring is too small for my current water bottle/jug. Anyone have a good recommendation?

I run a Nalgene bottle mostly. Day long trips I do a bladder water bottle do I can ice lots of water.

Second the nalgene, specifically the 48oz. Fits like a glove and carries enough for a full day of fishing

I’ve had good luck with the 32oz Hydro Flask in the left cup holder, fits snug but easy to grab. For quick trips, I just toss in a couple of plastic bottled waters since they fit the smaller ring perfectly. https://bottledevents.com/ has some helpful info if you're looking into bottled options. I also stash a water bladder in the hatch for backup on longer days.
