WeatherTech FloorLiner — Rivian R1S Review — The legacy heavyweight gets undercut by newer, more affordable competitors that offer better vehicle-specific bundles

WeatherTech's legendary floor mats are thick and durable, but Rivian owners are finding better value elsewhere. You’ve likely heard the name whispered in every automotive forum as the gold standard for interior protection, but when you drop a six-figure electric SUV into the mix, the math on these mats starts to look a little shaky.

What you're actually getting

When you pull these mats out of the box, you immediately notice the heft. WeatherTech isn't messing around with thin, flimsy plastic; these are thick, industrial-grade liners that feel like they could survive a nuclear winter. As Shooting Cars noted, "This is a lot thicker and a little bit more durable" than most of the competition. If your primary goal is to protect your Rivian’s carpet from heavy-duty abuse, mud, and salt, the sheer structural integrity of the material is hard to beat. They utilize the factory snap rings perfectly, meaning they aren't going to slide around while you’re navigating a trail or just trying to get to work.

However, there is a catch that becomes apparent the moment you actually use them. The design philosophy here relies on high side walls to contain spills, but the actual footbed is relatively flat with shallow ridges. This is a design flaw for anyone living in a rainy or snowy climate. Because the ridges aren't deep enough to channel water away from your feet, you end up standing in a puddle. As Shooting Cars bluntly put it, "If you spill a little bit of water, your shoes are still going to get wet."

Then there is the value proposition. You are paying a premium—often north of $330—for the front and rear rows alone. Unlike many of the newer, direct-to-consumer brands popping up for the Rivian platform, WeatherTech doesn't include a cargo liner in their kit. When you compare this to competitors like LinerX, which often bundles the entire interior protection package for less than the cost of just the WeatherTech floor mats, the decision becomes much harder to justify.

Performance — what reviewers actually measured

Where it actually wins

The biggest win for WeatherTech remains its manufacturing pedigree and fitment precision. Because they use high-tech CAD scanning, the mats hug the contours of the R1S floorboards with surgical accuracy. If you are the type of owner who values "Made in America" manufacturing and wants a product that feels like a permanent, structural addition to the vehicle rather than an accessory, these are the mats for you.

The high side walls are also genuinely impressive. If you’re prone to spilling coffee or tracking in thick mud, the containment area is massive. They act like a bathtub for your floorboards, ensuring that whatever mess you bring inside stays trapped within the perimeter of the mat. For someone who works on job sites or spends weekends in the backcountry, that level of containment is a legitimate benefit that keeps your resale value high.

Where it falls short

The lack of a cargo liner is the most glaring omission. The Rivian R1S is a utility vehicle; the trunk space is half the point of owning one. Expecting a buyer to spend over $300 on floor mats and then go elsewhere to find a matching cargo liner feels like a relic of an older business model. It’s inconvenient, and it makes the total cost of ownership for a full interior protection set significantly higher than it needs to be.

Furthermore, the shallow ridge design is a genuine frustration. In a vehicle like the R1S, you expect a certain level of thoughtful engineering. When you step into the car with wet boots, you want the water to drain into channels, not pool around your heels. It’s a design that favors aesthetic simplicity over functional water management, and it’s a point where newer competitors have clearly outpaced the legacy giant.

Should you buy it?

Buy if you:

• Value American-made products and want the thickest, most rigid material on the market.
• Prioritize high side walls for maximum spill containment.
• Don't mind paying a premium for a brand with a long-standing reputation for durability.

Skip if you:

• Want a complete, one-stop-shop solution that includes a cargo liner.
• Live in a wet climate and need deep channels to keep your feet dry.
• Are looking for the best price-to-performance ratio for your Rivian.

WeatherTech offers premium thickness and high walls, but its steep price and lack of a Rivian cargo liner make competitors highly appealing.
