My name's Brandon and I've been using a Chase Harper Barrel Bag on my 1986 XR600R for about a year now and I have nothing but good things to say! I also had one on my 1986 CR125 for some time.
They both have held up through anything I've thrown at them. No rips or tears, the color has surprisingly stayed very vibrant despite the Southern California sun. The zippers in particular have worked very well, never getting snagged or stuck even when covered in dust and dirt.
One feature that I love on the Barrel Bag is that it is reinforced with a very thick plastic on the inside, so thick that I actually drill through them and mount them with bolts to my fender. Stays put and looks great!
Again thanks a lot for a quality product, I can't wait to hear back from y'all so I can make my next order!
