Had to buy another one and stack them. Lots of space and very durable, and we pack them tight! Has a nice rain cover also.
From glad to happy I would make a couple suggestions: 1) Provide built in base support from one end to the other. What happens is the traditional luggage rack is narrower than the bottom of the bag, this allows in due time for the bag to sag a bit on both ends. 2) The black dye seems to fade quicker than I'd like. How about adding some UV protection to the heavy duty bag.
Fits my 2013 Honda Rancher well. I use it as a dust cover in barn, so it doesn't see heavier use others may use it for. Looks nice. It would normally cover all the way to the ground, but I have tool/loose item bins on my OEM racks, so it ends up exposing about 4-5" of wheels/tires - not a big deal for me.
The FastTrax BAckpack is nice, roomy and functional!
I ride an '06 CBR1000RR. Here in Northern Nevada it can be in the 30's in the morning and 80's in the afternoon. I was looking for a motorcycle pack that would hold my over pants and maybe my coat for the ride home in the evening. While this pack isn't big enough to get both my armored coat and armored pants into, it does fit the pants with the liner from my jacket along with my I-Pad Air 2. The pack seems to be very well made, nice heavy duty zippers and pulls. Ride safe!
