I ordered a set of these and they work pretty good. I will admit that I have not ridden them in temps below 40 yet. They install easy and are not too bulky. They are on sale at the moment 10% off I believe.
I agree! I have this bag and love it. I carry my wallet, phone, hat, camera and pair of gloves in mine. Still have plenty of room left .... Givi TankLock TPH02 Tank Bag - Street Bike - Motorcycle Superstore
