So I purchased a Giant Loop Bag for my GSA, brought it home and noticed a stitching defect. Called Giant Loop, and they remedied the problem quickly and with no problems, Thanks Harold with Giant Loop So I finally got the opportunity to put it on the bike, and the size of the bag is perfect for the odds and ends, camera, wallet, phone and so on. The bag came with a tube of seam seal to further weather proof it, construction is very nice, the material is made of a heavy coated "truck tarp" material very similar to a mags bags bag i had once (which was very bomb proof. Nice clear top for a map, cell phone and what have ya' Overall fit on the GSA is pretty good, plenty of room, and only slight interference with the cross bar on a stop to stop turn on the bars. The interior is nice and bright with a small divider in the back to keep things organized. I cant wait to get out and ride a bit and see how it works, this is the first tank bag i have had on this bike, I am not a fan of big tank bags, but this size is just right to me, and it is constructed to be fairly weather resistant. The bag zips along the base with a good quality heavy zipper, so refuling is no issue. The bag can be removed quickly while leaving the base. The bag has a nice grab handle, and is well thought out. I'll post some more feedback if anyone is interested.
