Overview:

The WeatherTech Rear FloorLiner is a precision-engineered interior accessory designed to provide complete protection for the rear carpet area of most Rivian R1S models from 2021 through 2026. Utilizing advanced digital laser measurements, this FloorLiner offers a perfect, custom fit that contours exactly to your vehicle’s interior surfaces. Ideal for daily drivers and outdoor enthusiasts alike, it safeguards your vehicle’s interior from water, mud, road salt, sand, and other debris, helping maintain a clean and well-preserved cabin environment.

Its thoughtful design ensures that trapped fluids are contained safely away from shoes and clothing, making cleanup effortless and mess-free.

Key Features:

The WeatherTech Rear FloorLiner combines innovative materials and design to deliver superior protection and convenience:

• Custom DigitalFit® design created from precise laser measurements for a perfect, edge-to-edge fit.
• Patent-pending High-Density Tri-Extruded (HDTE) material with a rigid core for strength and surface friction to keep the liner securely in place.
• Deeply sculpted channels and reservoirs that trap up to 1.5 quarts of water, mud, and debris, preventing spills and fluid movement during driving.
• Protective non-stick finish allows for quick and easy cleanup without staining or retaining odors.
• Anti-skid ridges on the underside prevent shifting and sliding on the carpeted floor.
• Made from 16 pounds of pliable, natural heavy-duty rubber that resists curling, cracking, and hardening in extreme cold.
• Designed specifically for the rear seating area of Rivian R1S Adventure and Explore trims from 2022 to 2024, with compatibility extending to all 2021–2026 models.
• Black color complements the vehicle’s interior while providing a sleek, professional appearance.

Construction & Design:

The FloorLiner is crafted from a proprietary High-Density Tri-Extruded (HDTE) material that features a rigid core for structural integrity combined with a textured surface to enhance grip and tactile feel. This tri-layer construction ensures durability and long-lasting performance under heavy use. The advanced channeling system is engineered to direct fluids and debris into a lower reservoir, minimizing fluid movement and preventing spills inside the vehicle. The liner’s edges are precisely contoured to fit snugly against the door sills and seat bases, providing comprehensive coverage without interfering with seat adjustments or door operation.

Installation & Fitment:

The WeatherTech Rear FloorLiner is designed for a straightforward, bolt-on installation with no cutting, drilling, or special tuning required. It fits securely over the factory carpet using the vehicle’s existing floor contours and retention points. This ensures a hassle-free upgrade that maintains the integrity of your Rivian R1S interior while providing maximum protection.
