does what it should with small drawbacks

The envelope in conjunction with a protective case I look for MTB use as a must.
With this combination, we are sure that with small falls that thing loses only limited to beauty.
Use very simple: covering - finished. Seat perfectly.
The only drawback: The opening at the bottom of the tailgate might also get a little cover if necessary. If you drive in the dirt, the front wheel meets this gap. Prior to each coupling the device you then try to clean this once.
