Car Roof Bag Bundle- 100% Waterproof Roof Top Cargo Bag NO Rack Needed + Non Slip Roof Mat & Storage Bag, for Any Car Van or SUV (15 Cubic Feet)

This is actually waterproof. Sat on the roof for over 2 hours of heavy rain, not even moisture got in.Ok, so to secure this your gonna want to keep logo towards the front of the car. You do want to try and fill the bag to keep it somewhat taunt. used a boogie board in the bag on top of my stuff to help secure and provide aerodynamics, and so not to crush my stuff. This helps in securing ratchet straps too. For waterproofing, make sure zippers are kept at end of zipper row after zipped, on side back, tucked in the corner.. like where the zipper ends, and flaps are down covering zipper rows. This will keep it waterproof.To secure I bought ratcheting straps. (for cars without roof rack like me) The ones that come with it (someone opened the box, maybe UPS? and I never got straps.) That's ok as I would recommend real ratcheting straps. Not worth losing everything on the road.1) The first thing is to lay down the mat on the roof. Then pack the bag, so the front of the bag is lower than the back of the bag. The lay down your boogie board, or whatever long, flat, hard "board" you have, place on top of your stuff in the bag. This will allow the ratchet straps to secure load without crushing your stuff or clothes. Plus it makes it aerodynamic. So the bag should look kind of like a triangle from the side. And it won't crush the bag so much, making it last longer.2) Ok, back to the straps. You want 1 strap to go from the front driver-side to the front passenger-side. Then another strap going from the rear driver-side to the rear passenger-side. Don't make an X! You will regret it. At the part where the straps go into the car, you can twist the straps to reduce vibrations while driving. Try to keep the straps that goe through the car in a spot where if they drip, they don't drip on your kids, or you. Like I didn't do. Kids loved the extra water play. IF it rains, they will drip if you are just doing this on a car, vs with a rood rack.

Let me start by saying my vehicle seats 8 and it has a way to add a roof rack but I didn’t want to spend the extra money on top of buying something to connect to the roof rack to hold our things. I finally made the move with my three children, my two nieces, my cat and my dog from CA to Texas. We sold our home in April and my husband went with his vehicle and another trip with the moving truck in Feb and April. I had stayed in CA until I had finished up some loose ends and in August I took what “little I had lived with left” um no. It ended up being 8 pieces of luggage, the animals, the kids, bedding items etc! I looked on amazon to find the cheapest way to make space and to pray the items got there and didn’t fly off. I drove to Arizona from CA with just my kids and picked up my nieces and got there late sorry the pictures are dark. We strapped the roof bag on and it held tight. No bad weather and rain or anything but as said in other reviews did hear a little wind as we drove. Nothing too crazy though. It held, no rips and the speed limit from AZ and in Texas is all 75-80mph. Never got loose, never moved and didn’t cause any damage or marks to my roof. Was hoping it would hold more items than we could put in but we made it work. The items were different shapes and sizes and with a bag you couldn’t stretch so of course we could only fit what would. With 6 people a large black lab and a bengal cat we needed the space. This allowed me to save money for my expensive move and drive not having to purchase a roof rack and then a hard large luggage carrier that I’d have to store somewhere later. It strapped on and folded up for storage when we got to our destination.

I purchased this to take on adventures and free up some space in my Ford Fiesta. A little background...my husband and I are pretty outdoorsy people. I'm also president of my university's climbing club. Since my car gets great gas mileage I often am one of the drivers for trips. However, my fiesta is rather small and packing for longer trips and hauling people at the same time was difficult and cramped. Well I am.happy to say those days are over. I purchased this before spring break this past year and I love it. For spring break a group of us travel from Maryland to Kentucky to climb for a week. We camp out the entire week so we have to pack all camping supplies and our climbing gear (and alcohol). As the most experienced person in our group, I often carry the group camping gear. You have to also consider it's spring break (March) so the weather is typically rainy or snowy and cold. I was able to fit our giant group tent, tarps, ropes, cooking supplies and climbing gear in this bag leaving plenty of room for people in the car. This past year it snowed and rained during break and not a single item got wet in the bag. Once tied down, the bag didn't slide or move an inch on my roof. It was also extremely easy to mount on the roof. Highly recommend for all your adventures!
