car pack
I have had only one opportunity to use it, but it was wonderful. I could pack a lot of stuff in that little bag.

Does the job well
We recently tested our karpak on a family vacation. Attached easily. Kept all belongings dry even through a rain storm. I used duct tape to secure loose ends of straps - this cut down on the flapping. One draw back is that I need a replacement strap and the manufacturer won't return my requests for information on how to obtain. I've used a generic strap but the specifically designed straps worked better.

Works well. Straps could be better. Needs a storage bag.
I used this on my 2003 durango. I had to move my luggage bar all the way to the back for it to fit properly. We took it on an emergency weekend trip to Amarillo with myself, the wife, four kids, and a puppy. We purchased a third row seat to accommodate everyone which left us without enough cargo room; thus the reason for purchasing this bag. We were able to fit a medium collapsed dog kennel, all of our luggage, and all of our bedding into this bag with room to spare. It worked very well.
My only two quirks with this product are the straps are unreliable and lack of a bag to store the cargo bag. Both of these are easily remedied.
My logic in buying this bag over other, more expensive bags, is that even if this bag did not last the full warranty time or if it had a defect form, it was still cheaper to replace it with another one than to buy the more expensive brands. I guess it all in the perspective.

Sturdy and Waterproof
I adjusted the cross-bars on the factory-installed roof-rack of our Toyota Sienna mini-van, put the KarPak between the bars, and packed it with clothes and snow-pants for six people. At that point, it was only half full. I strapped it down and tied off the loose strap ends. The entire procedure took twenty minutes, including reading the instructions. We set off in a cold rain storm. If we concentrated, we could hear the wind rushing around the bag at 70 mph, but there was no flapping of the plastic or the straps at all. Half-way there I opened the pack to get something out. I forgot to zip it up again and kept diving for another hour in the rain. But the plastic of the KarPak is sturdy and thick. There is a generous flap over the zipper. Even with the zipper undone and driving 70 miles an hour, hardly any water penetrated. With the zipper done up, we find it to be entirely water-proof. The zippers worked fine at 28F with the bag covered with snow. There are two zippers, and we found we could lock the bag by passing the bar of a standard combination lock through the zipper pulls. To get into the bag when it's locked like that, you would need a sharp knife and a strong arm. Maybe we would not leave the bag outside on the car with valuables inside on an inner-city street, but in a car-park in daylight we were perfectly content to leave it. For our trip of 380 miles in brisk cross-winds, we used roughly 20 gallons of gas, for 19 mpg with the KarPak's added resistance on the roof. That's pretty much the same as we get without the KarPak. Maybe we can get 22 mpg on a calm day on a flat highway. All round: we are delighted with the KarPak, and recommend it without reservation.

great deal
I purchased this carrier bag for my move to Texas and it did a wonderful job. My rack was a bit small for the bag, but it held on nicely for 1300 miles when completely full. Without the specialized bags, it didn't hold its shape very well, but the straps supplied did a fine job of holding on.

The straps get a bit noisy if not tied off or pinned down, and every once in a while something would bump the roof and make a funny noise, but no damage to the car or things inside. And the waterproofing did a good job. Nothing was wet inside even though it sprinkled a bit during the drive.
