WeatherTech tested patterns for every conceivable make and model of current popular vehicles to determine the best combination of ideal fit and score lines. The score lines can be easily cut with scissors so you can tailor your mats for a true custom fit.These mats have tall outer ridges and channels to help guide fluids to the lower half of the mat. Fluid then collects in a deep containment reservoir that traps fluid and debris away from your feet and clothe.WeatherTech is committed to the environment, so these mats are manufactured from a rubber compound that is virtually odorless and contains no harmful PVCs, cadmium or lead, and is 100% recyclable.
