I Bought & Tested the Best-Selling Truck Bed Tarps. Here's Why Cargolith is #1:
Written by Jake Thornton
That soggy drive home was only the beginning. Over the next three weeks I tried everything: a canvas tarp from a hardware store, a bungee net that let every raindrop through, and a roll-up cover that sagged like a hammock. Each fix solved one problem and created another, and I was still pulling over every hour to re-tension straps.
I've tested more than 40 truck cargo covers and tie-down systems over the years, so I know what a good one should do. It should stay dry in a downpour, stay quiet at highway speed, and let me reach my gear without a ten-minute strap ritual. Nothing I owned managed all three.
So I stopped guessing and set up a proper head-to-head. I picked the five most promising truck bed tarps, fitted each to my own pickup, and committed to six weeks of storms, highway miles and gravel roads. One of them had me quietly retiring my old tarps halfway through.
Here's what I found.
My Test Results
Over six weeks, I fitted each tarp to my own half-ton pickup with a 6.5-foot bed and treated them all the same. Every cover endured three overnight storms, a 30-minute hose-down that simulated driving rain, roughly 600 highway miles at 65 to 75 mph, and a rutted forest-road run to see what vibration does to buckles and seams. I also timed every install and teardown.
We scored each tarp on four criteria: Weather Protection (seams, coating and moisture under the cover), Fabric Toughness (abrasion, edge stitching and corner strength), Highway Stability (flutter, tension retention and paint contact), and Setup & Access (install time, reaching cargo and packing away). Our team logged everything in a shared spreadsheet, and I re-checked tension and moisture at every fuel stop.
The first surprise was how decisively Cargolith handled water. After the 30-minute hose-down, the cargo area underneath was completely dry, and the coated Oxford surface shed water so well that it was dry within minutes of the sun coming out. Two rivals showed damp patches along their seams.
Highway stability was the second win. The four-sided strap system kept the tarp planted at 70 mph with no visible flutter, and the tension I set at the start of a 150-mile leg was still there when I stopped. The zipper let me pull out a toolbox mid-drizzle without getting anything wet, and the silver underside kept a parked cargo box about 15°F cooler than the dark-lined rivals.
The limitations are small. The zipper needs a firm tug the first few times, and you have to measure your bed before ordering, since a loose fit undermines any strap system. Neither came close to a deal-breaker. My only real frustration was availability, because demand regularly outruns supply.
The Results:
After six weeks, Cargolith was the only cover that never made me pull over, re-tighten or worry about the forecast.
Value
Since fitting this tarp, I've stopped replacing covers every season, stopped wrapping gear in garbage bags, and stopped pulling over to fix flapping straps. That adds up to hours reclaimed each month, and it's why I see the purchase as a smart investment that pays for itself quickly.
Doing nothing has a cost too. Soaked sleeping bags, swollen power-tool cases and shredded flimsy tarps pile up, and every cloudy forecast becomes a source of stress. Temporary fixes like bungee nets and trash bags only delay the next failure.
Six weeks of storms, sun and gravel left no fraying, no seam leaks and no zipper trouble. The double-stitched edges and reinforced corner loops look built for several seasons, well beyond the thin covers I've watched fail in one. Check the store page for current warranty details. For anyone who hauls in real weather, this is a smart long-term decision.
From Weekend Campsites to Job Sites
With a dependable tarp, the forecast stops running your plans. I load up on Friday afternoon, strap down in minutes and drive off without checking the radar twice. Dry sleeping bags, a quiet cab and gear I can reach on the road are the small luxuries you notice most.
The benefits reach well beyond campers. Tradespeople protect tools and materials, hunters keep gear out of sight in public lots, gardeners haul mulch bags without a mess, and anyone moving house gets a dependable cover for boxes and furniture.
Customer Reviews
Hauled firewood and camp gear about 280 miles across the Rockies in steady sleet and everything came out dry. My old tarp would've been in shreds by mile 100. The zipper is a nice surprise, I grabbed my jacket without stopping.
Put it on by myself in about five minutes. No tools, no drilling. Fits my midsize pickup great.
I run a small fencing crew and our tools sit in the bed all day in brutal heat. The silver underside makes a real difference, my batteries aren't getting cooked anymore. The edge stitching still looks new after months of daily use, and I've stopped re-strapping at every stop.
Frequently Asked Questions
A truck bed tarp is a flexible, strap-down fabric cover that protects an open pickup bed and its cargo from rain, sun and road grime.
Unlike a rigid tonneau cover, it adapts to tall or oddly shaped loads, installs without drilling, and folds away when you don't need it.
It depends on the build. Coated Oxford fabric or vinyl with taped seams can keep cargo fully dry, while lightly water-resistant materials let moisture seep in at the stitching.
In my 30-minute hose-down test, only one of the five covers kept the entire cargo area completely dry.
A loose one can. Flapping fabric and slack bungee cords rub paint and tailgate edges at highway speed.
Pull the tarp tight on all sides, keep buckles and hooks away from painted surfaces, and re-check tension at your first fuel stop.
Measure from the bulkhead to the inside of the closed tailgate for length, and across the bed rails for width. Compare both numbers to the manufacturer's size chart.
A cover that's too loose will flap, and one that's too tight can strain the corner loops.
Yes, if the strap system pulls the fabric tight on every side. In my testing, a four-sided buckle setup stayed silent at 70 mph, while bungee-only designs began to flutter in crosswinds.
Always re-check tension after the first few miles.
Pitch is everything. Arrange cargo so the center sits higher than the edges, and keep the fabric taut so rain runs off instead of collecting.
Pooling is common on flat loads under looser covers, and standing water can stress seams.
A well-made cover with UV-resistant fabric, double-stitched edges and reinforced corner loops can last several seasons. Thin poly tarps often fray or fade within one.
Inspect the stitching and buckles every few months, especially after heavy sun exposure.
Demand for Cargolith regularly outpaces supply, so it does sell out. I waited about two weeks before I could place my own order.
If the official store page shows it available, I'd order right away.
Purchase and Delivery Process
Ordering is straightforward. Cargolith is sold exclusively online through its official store, which means no retail markups and no wandering auto-parts aisles.
The catch is demand. It's frequently out of stock, and I had to wait two weeks after it sold out before I could place my own order.
If it's available when you read this, order now rather than waiting for the next restock, which tends to disappear quickly.
Once you check out, delivery is fast, and setup takes just a few minutes.
