This is the Ultimate bag in black and blue, with a shape we're proud of: lower at the nose and taller at the tail, so air slips over instead of slamming into it. That means less hum at 70 and a little less fuel burned getting to the lake.

Ultimate 20 Cu Ft, Blue — shaped by the wind

Shaped by the wind

We tapered the front so the bag doesn't act like a sail. You'll notice it most on long interstate stretches, where a boxy bag drones and ours stays quiet.

Ultimate 20 Cu Ft, Blue — strong where it counts

Strong where it counts

Straps that hold 3,100 lbs of tension aren't about what you pack. They're about the one gust on the bridge you won't have to think about.

Questions from the road

Will it work over a panoramic sunroof?

Yes. Lay the non-slip mat down first, and the hooks go on the door frames, not the glass.

Same bag as the orange one?

Same Ultimate construction and capacity, in a blue colorway with the wedge profile.
