Fits a Nalgene. Wiggles around in the factory cup holders. Still better than not having it.

It holds a Nalgene bottle nicely. It is nice to have it close, isolating the condensation and not rolling off the passenger seat then all over the floorboards. Did someone on here mention an adapter to make it fit better inside the car’s cup holder? My cup holders are good sized but not large enough for a Nalgene so, the adapter wiggles and shifts around. Did someone mentioned that theirs cane with one? If so, where can I get them? Should mine have come with them?
