Supposedly the rear wind screen would help with that. Its a mesh screen that goes behind the seats, Can-Am makes one. I believe the Limited models come with them.

 

Mine gets dusty also but we live with it. Half windshield and a mesh screen on ours. My 2 cent would be a fold down half windshield like the polaris rzr has. At least you wold see the trail better. Still a great ride! My wife will no longer ride on the outlander.
Don't close off the back without closing the front. You may want to try removing the half front windshield. I have not tried it but heard it helps a lot. Don't know for sure though.

 

Got a question for you

I'm newbie with an XT 1000

When I ordered the SxS , salesman explained me the benefit of having the rear mesh screen when using a windshield (any type)

I have a bimini roof (soft, retractable) and being fully deployed or not, I have none experience with dust coming back in the cockpit.

So the question is, what kind of accessories you have with your Commander ?

 

I also have a major problem with dust in the cab. We can't ride without goggles and bandanas on. I also have the half windshield. I'm going to plug the floorboard drain holes and remove the windshield and see if that helps. I'll let you know.

 

Update on dust issue, we went ride at Bon Temps ATV park in Basile ,LA yesterday and I took off the half windshield. No dust issues, didn't need goggles or bandanas. Very enjoyable ride. Hope this helped.

 

True, it is the windshield that is causing the problem. It creates a negative pressure behind the windshield that draws dust into the cab. I found this same problem when a friend and I went for a ride with our identical side by sides. After the first ten miles we stopped to talk. My side by side had a half windshield, and the entire interior of my side by side was coated with a think choking layer of dust. I walked over to his side by side to talk to him, and his side by side had no dust inside the cab at all, and his side by side did not have a windshield on it. I was shocked at how much difference the windshield made as far as dust in the cab is concerned, so after that trip I removed my half windshield. From then on, no more problems with dust in the cab.

 

Lov the dirt!!

I put a windshield in mine but before that I installed a clear back window .. Big help! Stops a lot of blow through .. Front window is nice to..
