Experience with BMW Function Backpack

[KTsRidin]

Okay, a bit ago BMW came out with a backpack that has a "waterproof" main compartment, a padded area for a computer/files and a drop-down area that can either be added to the main area or be used for helmet storage. At $119 it's really steep, but I've got a 15% coupon for BMW stuff an am considering this.

 

So, does anyone have any experience using the BMW Function Backpack?

 

Thanks!
