Dont buy the special

this is kind of a misleading item. They come with cheap straps. Great product made for a bad experience with replacing the high end straps with cheap straps to get the price lower to get people to buy. Bad Deal. The Whispbar system is great, the strap are crap.

Expensive but well worth it. I have a TESLA Model S and they offer the Whisbar system for the car. I purchased the Kayak holders for the system. They are very cool, secure, and easy to use. Mounted them on the bar in just a few minutes (4) and you can even leave them on the bar as they fold flat. Very cool product.
