Haven’t had the opportunity to use them yet.
The bags are what I was looking at, they fit perfect on my bike and they secure with their straps, I will only add some air valves for when you don't have a lot to pack, in conclusion they are perfect for my CRF1100 Africa Twin.
I chose the medium size because of the low mounting and ability to mate with other bags for different length trips. They were relatively easy to mount on my FE501S with the True North Moto rear rack, though of course it took a few adjustments on the first ride to get them in just the right spot. They weight rides low and they are easy to squish down for a less than full load. I ended up running the main straps under my saddle because my tall, wide foam butt pad was too soft to keep the bags in a consistent place and they are more at home there anyway. Mounted in this way they are not easy to take off and remount, so don't expect to pop them off and drag them into your motel room but that wouldn't be too bad if you put the straps over the saddle.
The construction is very tough and I like that they are waterproof without an additional liner.
Great quality that exceeded expectations. Excellent thought thru design that fits perfectly on my 690r...honestly, they fit like they were customed designed for the bike. Especially liked the lightwt over all the other systems out there. Why add 10-15 lbs of weight just for empty bags? You might as well have hard bags in that case. Well done....
First of all, I have to say that the quality of the bags are excellent, after that, I did only one demo ride with my large blizzard and xl tornado bag combo in my Honda cb500x and it work very well.
