Five stars for quality of construction and thoughtful design. Seems like a solid value.
I bought the 26 cu. ft. bag with ratchet tiedowns for use in my 2010 Ford F-150. This is one of those products that seems like a lot for the money. Very heavy material, large zippers, robust stitching around the tie-downs and the FOUR BIG HANDLES that make carrying easy. The zipper shroud is substantial and should protect cargo from a heavy downpour, dirt, or mud. This is the perfect solution for a couple that likes to tent camp and isn't greatly concerned about security - - anything of much value will go in the truck cab. Easily enough room for two stuffed backpacks, coolers, and more. An ample stuff bag is included, as is waterproof grease for the zipper, which I used immediately. Based on testing the zippers, I would say don't go around the 90 degree corners if you don't have to - - that's where some hang can occur. The mouth of the bag is plenty wide. If problems arise after some long-distance traveling, I'll update my review accordingly. Happy with what I see.

Great product
Used this for an 8 hour road trip to and from Orlando. We went through storms and no water got inside. Highly recommend if you need to pack suitcases in your truck bed. Plenty space was able to pack 4 large suitcases plus 2 cheer competition bags and beach stuff.

Truck bed dry bag
Basically this is a big dry bag like you might take camping or canoeing. Itโs sturdy and very roomy. Material is high grade. I have a five foot bed for my mid size truck and it fits perfectly. It came with netting and a bag of carabiners. The net is good quality but the carabiners are pretty weak. One broke already. Other than that I am very pleased and would recommend.

Needs more glue or stitching at the seams.
I purchased the bag in 2025. It worked well during the first couple of trips. However, things must have shifted in the bag during my June 2026 trip from Minnesota. The seam blew-out (see pictures) and things did get wet. Fortunately, nothing was ruined - Iโm just out the cost of the bag. Unfortunately the Amazon return window had closed and I was unable to find any information on the internet to contact the manufacturer. Therefore, I will be looking for a different truck bed bag option before my next trip. This is my first ever review for an Amazon purchase. Hope it helps.

I don't give 5 stars away like candy.
I'm giving this 5 stars because it met or exceeded my expectations in every way (even some I didn't realize I had until I used it). There's not a bad thing to say, even if I tried. - Durability - it comes with patches and glue, but honestly I don't think I'll ever need it. Extremely thick and durable material - I would struggle to put a hole through it if I tried. The seams are quality too. - Waterproof - I drove through several torrential rainstorms, the kind that bring interstate traffic to a crawl with hazard lights on, and it didn't leak a drop. The zippers are thick and high quality, and are protected under a strip of material that velcros over them. - Volume - This is meant for a truck bed - not the roof of a sedan. As you can see in the photo, I easily put a family of 5's suite cases (1 lrg & 4 med) and still had room for a few other large items (another suite case if I wanted). And there was still headroom to stuff more small/soft things on top of the suite cases. - Ease of use - Unlike other models I noticed when shopping around, the zipper on this goes fully around 3 sides. So you can easily load it from the top, instead of stuffing suite cases in from one end. It also has handles on the side so you can load it on the ground and then lift it into the truck (with help - very heavy!!). - Bonus items - The elastic net and carabiner clips were great for holding other items down in my truck, like surfboards that would otherwise try to fly away. (Other models instead give you ratchet straps to hold the bag down, but honestly whats the point in that? It's not going anywhere when full. )

Great zippers and keeps gear dry.
Much better construction and zippers than other brand. Weโre not a cap family yet as we use our truck for more โtruckโ work. This is great when you clean out the tools and gear for the family trips. Keeps the luggage dry. I like the straps to keep it from going flying when we have to slam on the brakes or we hit a Dukes Of Hazzars jump on the way!

Started good, but after 1 year disappointed - It leaks considerably
I purchased the MARKSIGN 100% Waterproof Truck Cargo Bag with Net 1 year ago. I was looking for a solution to haul luggage and tools in our truck. Several trips to Florida in 2019 no problem and we were very happy. Noticed the last trip down November 2019 there was a little water inside the bag. Thought maybe I did not have it zipped completely so was not worried. We went down March 2020, got a lot of rain on the way, open the bag and there was considerable water inside. Enough it puddled and tools and bags were wet where they were setting. The zippers were fully closed and the velcro was down covering the zippers. Looked for holes and could not find any. When we came home in May same issue. Again considerable water inside the bag. I would not mind a small amount of water, but this is considerable. I looked very closely again for any holes and have as of yet to find any. This is unfortunate because other than the leaks (which is the main purpose of the bag) I loved it. The cargo net is still handy.

Great Waterproof Cargo Bag
This waterproof cargo bag is fantastic! I really appreciate the ability to anchor the bag to the anchor points in my truck bed. The zipper is durable and the way the top Velcro's over the zipper works really well. The bag has kept my stuff dry every time. We've also used it to store the patio furniture padded seats, back, and pillows over the winter.
