# WeatherTech W691 Black Rear Row Set All Weather Floor Mats for 2021-2026 Mercedes-Benz Multiple Models

### Performance Overview

WeatherTech All-Weather Floor Mats are engineered to keep your carpet clean and your footwear away from the mud and grime brought about by the elements. The deep groove design provides a channel that not only keeps liquid, mud, salt and other grime away from the footwear but holds them in place to keep it from spilling over onto your vehicle's carpet. The All-Weather Floor Mat is made from advanced rubber-like Thermoplastic Elastomer (TPE) compound that is odorless, latex-free, comfortable to the touch, and best of all completely recyclable. The material holds its flexibility and nonstick make-up even through the coldest temperature. The bottom of the mat is equipped with anti-skid ridges to keep the mats in place no matter your driving style.
