let 1 Two motorcycle tours with this bag and functioned well.Easy to remove from base then carry bag using shoulder strap.As it sits separate from the base the rain cover can fit fully and protect better.Something not mentioned is the base is well padded which makes it very suitable for placing my camera equipment inside.Negative point is the webbing on top is stitched to bag in middle so you cannot place anything except smallest item in there - it basically makes it just for decoration not useable but rest of the bag is good.
