I have the air lite chaps on my road glide. They make excellent quality thick vinyl and go on and off in minutes with velcro. A very tight fit, and they are "model" specific. The best product of this type i've found both in quality and looks. Mesh vent for the motor too! Do a google search for air lite chaps.

 

I bought the HD bar and shield ones last month. I think they helped a lot.We went riding in north Ga. We were in weather in the 30's and without them I would not of rode well worth the money

 

I just tried the Road Spirit ones this weekend. They really do help. At the same time, I installed the batwing air deflectors

from HD. The combo is kick-***.

The road spirit ones are vinyl I guess. They are not something one would 'install' on a nice bike, know what I mean? But, they are absolutely great for what they are! They look fine on a nice cool/cold day, let me tell you. Construction looks to be nice enough, too.

I recommend them! Quick on/off with Velcro and small enough for added rain protection, just like previously stated.

 

Mine work great to keep my feet warm. If my feet get cold I'm done! For the money probably one of the best pieces I've bought for the bike.

 

The O.E. lowers like those on the Ultra Glide have vents to channel air to the motor plus they're not as large as the fabric ones.
