Honest review of this product: we traveled 1100 miles one way. Still have the return trip, i will update later. We were not gentle with this bag and I read many reviews and read the insert twice before using the bag. We purchased the bundle with mat and extra straps. We have a 2011 dodge Durango with OEM roof rails and cross bars. The straps are finicky to say the least but lasted just fine through 1100 miles. As other reviewers stated, they are a bit of a pain but they work well once you get everything cinched down. All roof rails are different and i found myself using 2 of the 8 on the back rails and the other 6 I actually took apart to place through smaller anchor holes along the rail in order to evenly distrubute the tension. This worked great and in addition to using the straps to go around the roof rails and bag lengthwise, the bag didnt move an inch or bounce at all the whole trip, no noise or noticable drag. The first day was stressful. We had never used the bag and it took a good hour to figure out the best way to pack and secure everything. We went 800 miles the first trip, trash bagged everything (3 carry on size suit cases packed completely full and 3 duffel bags.) I do not know how people got camping equipment in the bag or A pack n play because that would take way too much room up. In addition to trash bags we used an old comforter on top to fill the bag full and prevent flapping and hopefully soak up any moisture that got in. The first leg was fine no issues. Used the door jams and wheels to step on to load and unload and was no problem. I'm 5'8. Took about an hour the first time to load, and about 10 to 15 minutes to unload it and dismantle and pack the whole thing away (2 people). We stayed a few days and went on from there. It had been misting rain where we were staying. We did the same thing the second leg, trash bags and comforter on top. We ended up driving through tropical rainstorm cindy. 8 to 9 hours of torrential rain and wind, just over 300 miles with slow speeds and rest stops. We almost had to pull over several times because of the visibility and stopped to eat for over an hour. We arrived and the suitcases were humidified inside, the clothing felt a little cool and humid but not exactly what i would call damp or wet, which is to be expected. Did not smell bad at all. Just smelled like clothing. There was about a total of a quarter to half a cup of water in the bottom (like others stated in heavy rain). The only dampness was one duffel bag since it was the thinnest bag and we only had to put about half the clothes in the dryer for 10 minutes. I think had we put some kind of absorbent material in the bottom maybe a old blanket, it would have soaked it right up.I dont recommend putting anything in the bag that is electronic, makeup or things you dont want to get wet just as a precaution. I was surprised at people that put such items in the bag, as that is not a smart thing to do even if no water entered the bag. The bag on the roof will get very hot from sun..We checked the bag and found no holes or rips. Like i said we were NOT easy on this bag and tied it down tight and checked and tightened as needed when we stopped every 150 to 200 miles which is less than the instructions say to but if we stopped that much we would never get anywhere.I was impressed. Since it is easier to dismantle and store than a hard top i really liked this bag. It fits enough for a 4 person family on a weeklong trip but not much more. Great price. Even if it rips in 2 when we take it down the last time i would consider this a win. But i doubt it. This thing faired well and i think it has quite a bit of life left in it.It is NOT waterproof, but extremely water resistant. I said if i took thie bag down and 3 quarters of the stuff was dry i would be surprised. And turns out 95% is totally dry. Amazing.Edit: return trip, 1100 miles. Not a tear or worn spot just a bug collection lol. We strapped it down again, no mercy given to this bag, it came through like a champ. Had clean clothes to unpack and hang right up since we had just stayed at a place with a laundry room. Would buy again and again.

Update: Now that I read the instructions that came with the cargo bag (better late than never), I'm changing my rating from 4 to 5 stars. Reason being is that the instructions clearly state that the zipper should be facing the rear of the vehicle, and we had it facing the front. So that might explain the small amount of water that was found on the bottom inside of the bag upon our return home. I'm giving the bag the benefit of the doubt and assuming the water leakage issue was human error, not cargo bag technology construction error. And next time I'm going to read instructions before using a product and reviewing it, not after.This bag was so close to getting 5 stars, but got knocked down a star after opening it upon our return home. We used the bag from DC to Myrtle Beach and back. On the way home we hit some extended rain. Water got into the bag, albeit not a lot. The strange thing was only the bottom of the inside of the bag got damp, whereas the rest of the bag was dry inside. But that's the only problem we encountered with this bag, and for us it wasn't much of a problem (the things on the bottom that got wet were either in plastic bags or were beach items, so everything wet could easily be wiped dry). Other than that, the bag performed excellently. The bag is well made and durable. The zipper is heavy duty and there's a Velcro cover flap that covers the zipper for added protection from the elements. The way the unzips and opens makes it easy to load. The straps are durable and well attached to the bag and there are plenty straps (8) to keep the bag securely tied down. Our SUV does not have bars on the roof rack in the front or the back, only on the sides. Yet this bag was stable attached only to the side rack bars. Finally, this bag holds a lot -- a lot more than what I thought it would. Overall, this is a great cargo bag for the money. I would only caution that you pack anything that you don't want to get wet in plastic. (Update: Or have the zipper facing the rear of your car.)

仕様で91.4 x 91.4 x 45.7 cmとありますが、34in×34in×16inの箱の表記のほうが正解なので（86×86×41㎝）要注意です。さらに内法は82×82×39くらいです。単純計算で260Lくらい。当方INNOのﾙｰﾌﾗｯｸIN569（内法105㎝×100㎝）に乗せようとしたのでどうしても小さ目を選択となりましたが、予想以上に小さ目です。さらに写真をよく見ていただくと、ファスナーラインの上から絞られるような台形になってますので完全なスクエアではありません。当方型崩れ防止のために塩ビパイプで四角い骨を作ったのですがファスナーの高さで断念しました。試しに入ったものとしては①ｺｰﾙﾏﾝｲﾝﾅｰシート、②キャプテンスタッグEVAﾌｫｰﾑマットダブル×２、③キャプテンスタッグフロアマット×１、④ハイランダー2in1シュラフ×２＋他シュラフ2。多少伸びる素材なので柔らかい物は融通が利きますが、できればﾁｪｱも入れたかった。ともあれ、ｻｲｽﾞの表記がおかしいので星3にさせていただきます。

drove from Ontario, Canada to Orlando, FL with this on top of our car. Worked amazing! Nothing got wet, we also got a blanket to put under it and it didn't move. We had it strapped to our roof rack. Make sure it is full so there is no flapping or noise- we put extra blankets and things to fill in the gaps and only used bags and soft items to fill the bag. It was very secure and worked amazing. It is black rubbery type material so it does get hot in the sun- that was the only issue when in Florida since the sun was so hot, it was hard to get things in and zipped up because the material was very hot. But it worked amazing and the price was right! Love this!

I just drove across Canada from Fredericton to Calgary with this Keeper cargo bag on top of my my Subaru Outback. I am so impressed as we hit every weather condition from rain , snow and very heavy winds. I was concerned that it may get beaten up abit from the weather but it didn’t. The bag is in prime condition as good as new when we arrived at destination. Very impressed and highly recommend. It also stored a lot of belongings. More than I thought.

I purchased this bag for a trip to Oregon. On the way back we hit torrential rain. Not a drop inside the bag!It is roomy, easy to use and seems pretty durable. There are no security features to speak of, other than it being a pain for someone to get in to it, as you first would have to undo most of the buckles to unzip it.Overall, I would definitely recommend this product.

My husband insisted we needed one of these. I thought we didn’t. I was wrong. This is extremely handy and can be tucked away and easily put on if needed.We have a wheelchair accessible van for our daughter so we have almost no storage space inside our vehicle. This however gives us a ton of extra space when and if needed. We drove from Ontario to Disney World with our daughter recently and this certainly made it a lot easier!! We did take everything out of the bag at night just for peace of mind. It was easy to secure and we didn’t worry it was going to fly off. Nothing got wet during the intense rain we drove through either.All around happy with this! I’m off to read reviews for some sort of de-bug soap to help get all of the dead bugs off of it that accumulated during the ride!
