Best For Big Loads

G4Free Waterproof Car Top Carrier

If you’re looking for something that can be used to tackle big loads and offer plenty of storage capacity, then the G4Free Waterproof Car Top Carrier is a great choice. It has some sizeable dimensions, coming in at 55″x37″x15.8″ to enable you to take even oddly shaped and large cargo with you wherever you go. That size is also one of the biggest drawbacks of this bag, however, as it does restrict the kinds of vehicles that it can be used with. There’s basically no chance of a small or compact car being able to take the G4Free. It’s just too large to be securely mounted to them, roof rack, or no. Even some standard-sized cars may have trouble with this one. Make sure that the carrier is securely attached to the top of the car. If even a small amount of carrier hangs off over the roof, it’s a major security risk that can’t be ignored.


This bag can do some heavy lifting

The dual seam technology works incredibly well to provide a true waterproof experience. The straps and strong and wide, which means they are versatile. The top carrier works with and without roof racks to provide excellent support for large loads. It is incredibly durable and designed to protect your luggage from all conditions.

It’s a shame that the roof top carrier is limited by its size, given that it can be attached to cars without roof racks. It also comes with a total of ten straps for complete security. These straps are all tested to handle up to 3,000 pounds of pressure. This carrier should stay securely attached to any car, provided that it can be attached to it in the first place. The G4Free is made from a high-density polyester with a PVC coating. This is somewhat surprising given the price of the carrier. For that price, you’d expect something a little bit more durable – such as nylon.


  • Offers up to 18.5 cubic feet of storage
  • Large dimensions to make room for cargo of all shapes and sizes
  • 10 security straps tested to 3,000 pounds of pressure mean that security is not an issue here


  • As spacious as the carrier is, that space makes it too large for some vehicles

The price is a little high considering the material and demand for this kind of product
