Dutch version, works great

Looks good DJ although I prefer the Dutch version Those racks would let water in when it rains though I imagine. Similar issues when you strap anything through the car like that.

I think if the two top buttons were done up ted it would fine

Inflatable = even better for travel & rental cars. I like this product.

(^^^bit of a fan of the Dutch version, too)

New? 20kg?
Got a set in front of me by a company called handirack that claim they are the "worlds first inflato roof rack" and reckon they can hold 80kg. The panel work can still probably only support 20kg, but the racks will take more!
