Since the middle of 2018, the patch kit with the AirHawk R has been replaced with a lifetime warranty.
The rice-paper thin covering:

It has been replaced with a more robust and thicker woven material that encapsulates a thin layer of open-cell foam:

The bladder has been completely redesigned. It used to have a distribution of mostly uniform cells with a gap down the middle for your tail bone. It now has variety of shaped cells and a physical (and larger) cutout for the tail bone:

The price is roughly 1/2 of the previous generation Cruiser R. I haven't ridden on it yet but it looks like a winner at first glance.
If it's anything like its predecessor, you nestle this sweet peach of a cushion between a Sweet Cheeks (Coke Bottle) seat widener and your dual sport arse will be singing with glee without the smelly off-gas that normally accompanies a singing arse.
I still wish it came with a patch kit. Cats suck.
