  • Black
  • Custom Fit
  • Thermoplastic
  • WeatherTech
  • Contoured

Protect the interior of your trunk or cargo area with this weatherproof, impact-resistant liner. Advanced surfacing helps trap fluid and debris; textured surface holds mat securely in place; and custom design ensures a perfect fit for your vehicle.


Features:

  • Custom molding allows for complete coverage of your trunk or cargo area
  • Advanced surfacing provides channels to trap fluids and debris for easy cleanup
  • Raised side lip keeps spills contained
  • Unique material is formulated for durability
  • Textured surface securely grips the floor and holds your cargo in place during transit
  • Black finish complements most interiors
  • Made in the USA


Your vehicle not only gets you from point "A" to point "B"; it also allows you to transport people and pets or to haul luggage, lumber, outdoor gear, groceries, plants and more. And all this activity deposits dirt and grime, damaging your interior. Protect it with a WeatherTech Cargo Liner. Digitally designed to fit every contour of your trunk area, this custom liner is constructed of TPO - a weatherproof, impact-resistant material made to last. The cargo mat features a textured finish that helps to prevent items from shifting during travel. And the raised lip and channels provide barriers to stop liquids from spilling onto the carpet, making it easier to clean up messes.

by:

The lip around the edge doesn’t really hold its shape to well to contain liquids, and the bottom has no spikes or traction, so the whole thing slides on the carpet. It slowly slides toward the door, and then the door doesn’t close. Good material I guess, but really poor design. Ill buy a different one as soon as I catch my breath after paying WeatherTech prices for something that doesn’t do the job.



by:

This cargo liner is fantastic!

The
fit is precise and matches the trunk of my car exactly. It is slightly thinner than I was expecting, but the liner is very light yet stiffer than regular floor mats. The light and fairly flexible material makes for quick add/remove easing cleanup. Edges around the entire perimeter are over 1" tall and will hold a significant amount of water/dirt/whatever without destroying the trunk.



by:

Exact fitment. Quick shipping from etrailer. Made for my car. Looks like a factory accessory. I would recommend both the Weathertech custom floor mats and etrailer for the positive shopping experience I had.



by:

Heavy duty protection that works great.



by:

Mat fit my 2017 Tahoe perfectly, can't be happier with fit and performance. Great product



by:

It does not fit. When I called to complain I was told to just cut the corner off and then it would fit. Your ads say they are laser measured to fit perfectly, the cargo liner does not fit!



by:

Looks and fits great



by:

This is a great quality product. It fits my 2014 Highlander Limited perfectly. Also, I was very pleased with etrailer.com shipping my cargo liner right away. I selected regular ground shipping, and the product came pretty quick. Thank you!



by:

When I received the mat, I warmed it in the sun to soften it and dropped it into place for a perfect fit in the kinda quirky space of a Bolt EV. It's especially handy on a nursery run when we come back with dripping wet plants with soil attached. Just pop it out, dump out the water, soil, etc and pop it back in. After a year of faithful service, we highly recommend this product.



by:

Perfect fit for the 2025 Lexus GX 550 6 seater model, given Lexus does not make a large cargo mat/liner. Just let it sit out in the sun for 5 mins and it will unfurl and be ready tor installation.



by:

I purchased the WeatherTech mats for the front and for the cargo area of my '17 Chevy Bolt. The front floor mats fit perfectly once they were warmed up in the house to make them more flexible. To me, WeatherTechs are more plastic-like than rubber-like but they do the job. I had issues with the cargo mat. Be aware that there are different mats for the "false floor" and the floor in the cargo well for the Bolt and this wasn't clear at the time of my purchase. Make sure you know which mat you want to save return and repurchase.



by:

Perfect fit



by:

The WeatherTech liner fits well in the back of our new Toyota Sienna and provides the protection we wanted for the interior when we travel. We normally stow the third row seats since it's just the wife, dog, and I travelling so the mat protects the stowed seats/carpet from the soiling and wear/tear of our luggage, gear, etc.
We are extremely pleased with both the product and the great service.



by:

great product



by:

I very much like etrailer (vendor) but this particular product (weather tech cargo liner) does not meet my full expectations. It fits nicely in vehicle when 3rd row seating is folded down but when 3rd row seating is up you have to remove the weather tech cargo liner. The OEM version from KIA has a fold such that when the 3rd row seating is raised, the cargo liner simply folds back on itself (and fits nicely regardless if the 3rd row is up or down).



by:

Works real good another Weather tech product you can count on



by:

Perfect fit



by:

Fits perfectly



by:

This cargo liner is not what we expected. Small for the price.



by:

Excellent product, fit perfectly. Attentive and engaged service (seldom seen these days), fast delivery. Very pleased. Already ordered another product from etrailer. Thanks folks.



by:

Nice fit for 2025 Honda Civic Sport Hybrid. Will contain muddy boots nicely in the trunk.



by:

Just installed it fits well it was kinda rolled up so it still isn't laying flat but I'm sure it'll get sorted out



by:

Great floor mat that fits perfect



by:

The weather tech floor mats fit perfectly. The delivery was great and prompt as well.



by:

I love the fit and durability of the WeatherTech Cargo liner. It came rolled up, but after unrolling and setting two coolers overnight on top of it to straighten, it lies flat in the back of my Pilot perfectly.

  • Will Floor Mats from a 2007 Honda Pilot Fit a 2009 Honda Pilot
    The first generation Honda Pilot was from 2003-2008 and the second generation Honda Pilot was from 2009-2015. Since a 2007 Honda Pilot is a different generation than a 2009 Honda Pilot the floor mats will be different. For a 2007 Honda Pilot I recommend using part # WT440591 for the front, part # WT440222 for the rear, and part # WT40182 for the cargo area. For a 2009 Honda Pilot I recommend using part # WT441741 for the front, part # WT441742 for the rear, and part # WT40378 for the cargo...

  • 2015 Honda Pilot Cargo Mat Liner Recommendation
    The Weather Tech Cargo Mat part # WT40378 that you referenced will fit all the way up to the back of your second rows of seats when the third row of seats is folded down. Your best option would be to run the # WT40378 when you have the third row of seats folded down and then go with the part # WT11AVMCB for when you have the third row folded up.

  • Will Husky Liner WeatherBeater Stay Put and Keep Groceries from Moving in a 2011 Honda Pilot
    So far we haven't received complaints of the Husky Liners WeatherBeater # HL24361 allowing bags of groceries to slide around but then again this isn't really guaranteed to keep stuff immobile. It will definitely be better than the current surface in the back of your 2011 Honda Pilot but it isn't really "sticky". This liner will be too rigid to roll up if you are needing to use a 3rd row of seating in your Pilot but we do have the WeatherTech # WT40378 which is flexible enough for you to...

  • Is Cargo Mat Compatible With Third row Seating on 2015 Honda Pilot?
    The WeatherTech Cargo Liner # WT42378 will roll up when you want to use additional third row seating with your 2015 Honda Pilot. These liners are a custom fit for your vehicle and also come in black # WT40378 and tan # WT41378.

  • WeatherTech Cargo Liner for 2015 Honda Pilot
    WeatherTech's Black Cargo Area Mat # WT40378, as well as the tan # WT41378 and grey # WT42378 versions, is intended to fill the space between the backs of the 2nd row seats and the far rear of the vehicle interior. This covers fits if the 3rd row seats are folded down.

  • Availability of Highland Cargo Mat to Fit 2012 Honda Pilot From Second Row Seats to Back of Vehicle
    The Highland cargo mat that will fit your 2012 Honda Pilot from behind the second row of seats to the back of the vehicle is the Highland Universal Cargo Mat, part # 46045. This cargo mat is black and is a universal design mat. I also have two custom fit cargo mats for your vehicle. The WeatherTech Cargo Liner, part # WT40378, in black and the Husky WeatherBeater Cargo Liner, part # HL24361, in black. They will also cover from behind the second row of seats to the back of the vehicle.

  • Cargo Liner Function With 3rd Row Seat On 2010 Honda Pilot
    For the 3rd row use in your 2010 Honda Pilot, I reached out to my contact at Husky Liners and the WeatherBeater Custom Cargo Liner # HL24361 is too rigid for use with the 3rd row, the cargo liner would need to be removed. I also reached out to WeatherTech and the WeatherTech Cargo Liner - Black # WT40378 will allow you to roll it up when you use the 3rd row seat and it comes shipped rolled up in this way, however, they don't recommend you keep it rolled up for long periods of time (2-3...
