The moment we took delivery of our Rivian R1S, an immediate wave of protectiveness washed over us. This isn’t just a vehicle; it’s a masterpiece of engineering, a gateway to adventure, and a significant investment. The interior, with its clean lines and premium materials, feels more like a minimalist lounge than a utility vehicle. But the reality of owning an SUV, especially one as capable as the R1S, is that life gets messy. Weekend trips mean muddy hiking boots, beach days bring back half the shoreline in sand, and even a simple grocery run can end with a leaky milk carton. The beautiful, carpeted cargo area behind the third-row seats is a pristine canvas, but it’s also the first line of defense against the chaos of an active lifestyle. Leaving it unprotected felt like a ticking time bomb, waiting for the first inevitable spill or scratch to mar its perfection.
- Perfect Fitment: BestEvMod for Rivian R1S trunk mat is designed according to the original vehicle in 1:1 to make sure it fits your R1S perfectly.
- Premium TPE Material: Using high-quality TPE material to make it anti-slip, waterproof, durable, scratch-resistant and heavy duty. Good durability and a nice thickness ensure long-lasting usage.
What to Consider Before Buying a Cargo Liner
A cargo liner is more than just a piece of rubber; it’s a key solution for preserving your vehicle’s interior, maintaining its resale value, and simplifying your life. It acts as an impermeable barrier against spills, dirt, snow, and abrasions from heavy or sharp objects. For an electric SUV like the Rivian R1S, which often appeals to families and outdoor enthusiasts, a high-quality liner is an essential accessory. It transforms the cargo space from a delicate, carpeted area into a rugged, utilitarian hold, ready to take on anything from potted plants and sports equipment to pets and camping gear without a second thought.
The ideal customer for this type of product is a vehicle owner who sees their car as a tool for life’s adventures and wants to use it without hesitation. It’s for the parent with kids who spill, the dog owner whose furry friend loves muddy puddles, or the weekend warrior hauling gear to the mountains. Conversely, a custom-fit 3D liner might not be suitable for someone who rarely uses their cargo area or is content with a simple, generic flat mat. For those seeking absolute, edge-to-edge containment and a perfect, factory-like fit, a product like the BestEvMod Rivian R1S 3D Cargo Liner is precisely what they need.
Before investing, consider these crucial points in detail:
- Dimensions & Fit: This is paramount. A generic, “trim-to-fit” mat will never offer the same level of protection as a 3D liner created from a laser scan of your specific vehicle. Look for a liner that follows every contour of the floor, rises up the sides, and has precise cutouts for tie-down points or other features. An improper fit can lead to shifting and allow dirt and liquids to seep underneath.
- Coverage & Containment: A good cargo liner should feature a raised outer lip or edge. This design element is critical for containing spills, whether it’s melted snow from skis or a tipped cooler. The higher the lip, the more liquid it can hold, preventing moisture from ever reaching your vehicle’s carpet and causing mold or rust issues down the line.
- Materials & Durability: The material dictates the liner’s longevity and performance. Thermoplastic Elastomer (TPE) is a premium choice, offering a great balance of durability and flexibility. It’s more rigid than rubber, holds its shape well in extreme temperatures, and is typically odorless. Cheaper rubber can crack in the cold or emit unpleasant odors, while carpeted mats offer minimal protection against liquids.
- Ease of Use & Maintenance: The best accessories are the ones you don’t have to think about. A liner should be lightweight enough to install and remove easily for cleaning. Its surface should be non-porous and textured to prevent items from sliding excessively, yet smooth enough to be wiped down or hosed off without trapping debris in tiny crevices.
Keeping these factors in mind, the BestEvMod Rivian R1S 3D Cargo Liner stands out in several areas, particularly its use of TPE and its custom-molded design. You can explore its detailed specifications and see how it addresses each of these points here.

First Impressions: Unboxing the BestEvMod Rivian R1S 3D Cargo Liner
The liner arrived in a surprisingly compact box. As noted by several users, it comes folded to save on shipping space. Upon unboxing, our first action was to address the creases from packaging. Following the advice of fellow owners, we laid the mat out in the warm sun for a couple of hours. This trick worked wonders; the TPE material relaxed and flattened out, revealing its intended custom shape. The initial feel of the material is impressive. It has a satisfying heft—not so heavy as to be cumbersome, but substantial enough to feel durable and stay in place. It’s a semi-rigid material that feels premium, with a slight flexibility that makes installation easy. There was no discernible chemical smell, a common complaint with cheaper liners. The surface has a fine texture designed for grip, and the overall look is clean and minimalist, with no overt branding, which perfectly complements the Rivian’s sophisticated aesthetic.
What We Like
- Precision 3D fit that matches the R1S cargo contours perfectly.
- High-quality, durable, and odorless TPE material.
- Raised edges provide excellent containment for spills and dirt.
- Maintains full access to OEM tie-down anchors.
- Easy to install, remove, and clean.
Potential Drawbacks
- Arrives folded and requires time to flatten completely.
- Surface grip is good but may not prevent all items from sliding.
Deep Dive: A Comprehensive Performance Analysis
After several weeks of rigorous testing—encompassing everything from hardware store runs and muddy trailheads to hauling groceries for a family of four—we have a thorough understanding of where the BestEvMod Rivian R1S 3D Cargo Liner excels and where it has minor shortcomings. It’s a product that aims to blend OEM-level quality with aftermarket value, and for the most part, it succeeds brilliantly.
The Litmus Test: Fit, Finish, and Installation
The single most important attribute of a custom cargo liner is its fit, and this is where BestEvMod’s 1:1 ratio measurement process pays off. Once flattened, we placed the liner into the cargo area of our R1S (with the third row upright), and it dropped into place with satisfying precision. It’s a “fits like a glove” experience that many users have celebrated. The liner contours perfectly to the floor and walls of the trunk, leaving no significant gaps for dirt or debris to sneak under. The edges rise a few inches up the sides, creating a protective basin. Crucially, the cutouts for the factory tie-down anchors are perfectly placed, allowing full functionality without compromise. This is a detail that cheaper, less thoughtfully designed mats often miss.
However, the initial unboxing experience is a consistent theme in user feedback and our own testing. The mat absolutely needs time to decompress. While a few hours in the sun did the majority of the work for us, some users report needing a few days for stubborn creases to fully relax. In one case, a reviewer noted a crimp they couldn’t get to lie flat. While our test unit settled in perfectly, it’s clear that some patience is required post-unboxing. We found that placing a weighted object on any lingering high spots for a day helped it mold completely to the floor. The installation itself is tool-free and takes seconds—simply lay it in place. This simplicity is a major benefit, as it means you can easily remove it for a thorough cleaning whenever needed.
Material Science in Action: The TPE Advantage
The choice of Thermoplastic Elastomer (TPE) is what elevates the BestEvMod Rivian R1S 3D Cargo Liner above more basic alternatives. TPE is a fantastic material for this application. It provides a semi-rigid structure that holds its 3D shape, unlike flimsy rubber mats that can sag or deform over time. During our testing, we exposed it to both hot and cold conditions, and it remained perfectly pliable without becoming brittle or overly soft. It’s 100% waterproof, a claim we tested with a deliberate “spill” of a full water bottle. The liquid was perfectly contained by the raised edges, and we were able to lift the mat out and pour the water off with none of it reaching the vehicle’s carpet.
The material is also impressively scratch-resistant. We slid heavy plastic storage bins, wooden planks, and metal tools across its surface, and it shrugged off the abuse with no visible marks. One user praised the material’s sturdiness, noting it could “handle heavy loads and prevent any damage to the cargo area.” This is exactly the kind of peace of mind you want from a heavy-duty liner. While some reviewers mentioned that the mat can slide slightly on the carpeted floor, we found its weight and custom fit kept it largely in place during normal driving. For those concerned about this, a few small strips of hook-and-loop tape on the underside could provide extra security, though we didn’t find it necessary.
Everyday Usability and All-Weather Dominance
Beyond the technical specs, how does the liner perform in the real world? In a word: flawlessly. It has fundamentally changed how we use our R1S. There’s no longer any hesitation before throwing muddy gear or a wet dog towel in the back. Post-hike cleanup has gone from a tedious session with a vacuum and upholstery cleaner to a simple 30-second wipe-down with a damp cloth. For more serious messes, pulling the liner out and hosing it off is effortless thanks to its light weight (just over 3 lbs / 1.4 kg).
One user living in a snowy climate praised the “amazing coverage,” stating the “cloth is fully covered.” This is the core benefit. The high walls of the 3D design ensure that melted snow, sand, and dirt are fully contained within the mat. We found the surface texture strikes a good balance. As one reviewer noted, it “helps a little bit with stuff slipping… but not much.” Groceries in bags tend to stay put, but a single, smooth plastic box might slide around during spirited driving. It’s not a high-friction rubber surface, but rather a durable, easy-to-clean protective layer. The trade-off is that this smoother texture means debris doesn’t get trapped, making it incredibly easy to clean with a quick vacuum or wipe. The all-weather protection this liner offers is a must-have for any R1S owner who plans to use their vehicle as intended—for adventure.
What Other Users Are Saying
Our positive experience is largely mirrored by the broader community of owners. The sentiment is overwhelmingly favorable, with many reviewers awarding it five stars for its “super fit.” One user succinctly stated, “Fits like a glove!” while another was pleased with the value, noting “the abundance of mats you get for the price is worth it.” The clean, brand-free aesthetic is also a frequently mentioned positive, giving it a minimalist, OEM-like appearance inside the vehicle.
However, the feedback isn’t without its critiques, which provides a balanced picture. The most common issue, as we also experienced, revolves around the product arriving folded. Several users have expressed frustration that the mat “just doesn’t want to lay flat,” even after weeks in the sun. One reviewer noted their mat seemed “about 1/2″ too wide so the middle lifts up.” Another pointed out a potential design flaw: “there’s no lip edge at the middle (where the mat comes folded), so I suspect water or melted snow would just flow there onto the trunk.” While we didn’t experience this leakage, it’s a valid observation about the central crease. These comments highlight that while the design is excellent, manufacturing tolerances and shipping methods can lead to some minor but annoying fitment issues for a small subset of buyers.
How Does It Compare? The BestEvMod vs. The Competition
While the BestEvMod Rivian R1S 3D Cargo Liner is tailored for a specific vehicle, it’s helpful to see how it stacks up against other popular liners in the market to understand its place in the ecosystem of vehicle protection. The alternatives listed below are for different vehicles, so our comparison will focus on material, design philosophy, and features rather than direct fit.

The HAFIDI liner for the Hyundai Tucson occupies a similar market segment as the BestEvMod liner: a vehicle-specific, custom-fit solution at a competitive price point. Like the BestEvMod, it uses TPE material for durability and all-weather performance. Its design also features high walls for containment. Where the two might differ is in the finer details of the surface texture and the precision of the 3D scanning. For a Hyundai Tucson owner who wants dedicated protection without paying for a premium brand name, the HAFIDI is an excellent choice. It reinforces the idea that you no longer need to spend top dollar to get a perfectly molded, high-quality liner for your vehicle.

The powoq liner for the Toyota Highlander introduces an additional feature: included backrest mats. This is a significant advantage for users who frequently fold down their rear seats to expand cargo space. This design provides seamless protection for the backs of the seats, an area often overlooked. While the BestEvMod liner is designed specifically for when the R1S’s third row is *up*, the powoq demonstrates a different approach to comprehensive protection. A Highlander owner who regularly transports large or messy items with the seats down would find the powoq’s all-in-one solution more compelling than a simple trunk-only mat.
3. Kiwi Master Jeep Wrangler JK All Weather Cargo Mat

The Kiwi Master liner for the Jeep Wrangler JK is built for one of the most rugged vehicles on the road, and its design reflects that. It focuses on extreme durability and deep, aggressive channels to trap mud, water, and sand—hallmarks of the Jeep lifestyle. Compared to the BestEvMod’s more understated, clean design, the Kiwi Master is overtly utilitarian. This product would be preferred by a Jeep owner whose primary concern is trapping large amounts of off-road debris. It highlights how different brands tailor their aesthetics and features to the specific ethos of the vehicle they are designed for, from the sleek tech of a Rivian to the rugged functionality of a Wrangler.
Our Final Verdict: Is the BestEvMod Rivian R1S 3D Cargo Liner a Worthy Upgrade?
After extensive use and evaluation, we can confidently say that the BestEvMod Rivian R1S 3D Cargo Liner is an essential accessory for any R1S owner. It delivers on its promise of providing heavy-duty, all-weather protection with a fit and finish that rivals much more expensive options. The high-quality TPE material is durable, easy to clean, and perfectly suited for the demands of an active lifestyle. It masterfully bridges the gap between the R1S’s luxury interior and its adventurous capabilities, allowing you to use your vehicle to its fullest without fear of ruining the carpet.
While the initial need for the mat to flatten out after shipping is a minor inconvenience, the end result is a near-perfect fit that offers exceptional coverage and containment. For a fraction of the cost of some big-name brands, you get a product that performs its job brilliantly and looks great doing it. If you want to protect your investment and embrace every muddy, sandy, or spill-prone adventure that comes your way, this cargo liner is one of the smartest and most practical upgrades you can make for your Rivian R1S.
