Looking for Extended Rear Fender Flare

I have a 2015 900-S and would like to find a set of rear fender flare extensions.
I noticed that if I get on it at all in the mud that the main area throwing mud on me seems to me from the rear.
Seems to fling mud up and rain it down the back of my neck.

Anyone have any suggestions for extending the rear flares a bit?
My main riding is in tight woods, so I have to be cautious about them getting tore up on trees.
So I need something that might have some give to it, and that doesnt stick out TOO much.

Was also thinking about doing a rear window,,, would this be a more effective solution?
Though, it would be nice to prevent it from filling the bed with mud, which the rear window would not help.

Thanks.
