There are several manufacturers that provide ski carriers for vehicles. It is important to transport skis outside of the vehicle to prevent them from hitting passengers and causing severe injury in the event of an accident. These carriers can mount on trailer hitches or roofs. The design of each manufacturer is different and it is best to review their sites before you make your purchase. The sites will provide the options available for your vehicle and the advantages of the different styles you can choose from. Below is a list of manufacturers and the style of carriers they supply.
Roof boxes are fully enclosed carriers. This equipment is optimal because it protects your equipment from the elements such as sand, rocks and road salt. Unfortunately, they are also 3X the price but worth it if you have expensive gear. The one drawback of ski racks is your gear is fully exposed to the elements such as sand, rocks and road salt. If you choose a rack, just be sure to rinse and dry your gear when returning home to remove road salt that will corrode your edges. You can also use a bag to protect against debris but you will still need to rinse because most bags are not waterproof.

Be aware that there are different foot packs for different model vehicles and those with and without gutters. Typically the carrier manufacturer will only let you select the proper foot pack for your vehicle. Most attachable racks also have a layer of rubber or equivalent between the metal foot bed and the paint on your vehicle. This will protect your car from any scratches.
