Received my Explorer yesterday. Installed this morning, took all of 5 minutes.
Bag is not as large as I had feared. Footprint is nearly the same size as my Marsee mag bag, with the explorer being deeper. Made out heavy canvas, with all seams being heavy duty and well finished. Quality zippers, and plenty of velcro used throughout. Manufacturing quality appears equal to or better than my Marsee, and Nelson Rigg bags, far superior to my Joe Rocket Manta Bag.
Interior is finished in a light grey, with a key clip, and inside mesh pocket. Also has some type of pockets on each side.
Bottom is coated with some type of rubber material to prevent scratching.
Rear straps, from rider, are easily attached to bar behind steering head, with straaps run over filler panel.
Front straps, near rider are mounted under tank support.
Once the straps are mounted it is a simple process of hooking bag into all four buckles. The rear , away from rider, pulls down so "strap guards", are just about even with bottom of filler plate.
Front, rider side, leaves a very small gap at bottom of tank.
Here are several views with bag on bike.
