The water might get a little hotter than normal, but when your hot and thristy and you can't pull off, it comes in mighty handy. A coupla swallows and a little squirt on your neck and you can run another 50 miles. I only put mine on for long trips and I only have the one for the left side, but I use it a lot. My 09 Road Glide didn't come with saddle bag guards, I installed em just so I'd have a place to hang my water bottle pouch, that's how important it was to me, + I like the added protection, Lord knows that painted stuff ain't cheap. I don't believe the Passenger Comphort Saddle Bag Guards will accept the Harley Bag Guard Pouches though.
