BMW Soft Bag
I have the large version on my GS and I love it. GSDonavan did a good and accurate review. I would add that the straps to which the bag is mounted can be attached to your bike and left in place. All I need to do is throw the bag on the tail rack, click 4 straps and off I go - 30 seconds max. I have had other tail bags and top cases and so far, this is my favorite and it looks cool, IMHO.
Itís so hard to forget pain, but itís even harder to remember sweetness. We have no scar to show for happiness. We learn so little from peace.
