SoftTop

Super-affordable and easy to use, the Yakima SoftTop secures to vehicles with and without roof racks, instantly adding 12 cubic feet of storage for weekend excursions and long-distance road trips. Its naked roof straps attach directly onto the roof of your vehicle, meaning you can use this without a factory-equipped rack or costly crossbar setup. And because it's extremely versatile, it fits nicely inside Yakima's  MegaWarrior and LoadWarrior baskets, as well as any roof basket big enough to accommodate its dimensions.

Its weather-resistant construction protects your gear from intermittent showers and drizzly conditions. However, this bag isn't equipped to keep your gear dry through heavy deluges, so you'll need to put items inside a waterproof bag during soaking rains and nasty weather. And when you're finished using the SoftTop, quickly roll it up and stash it away to reduce unwanted drag and a loss in gas mileage associated with other roof rack setups.
