I do know Honda has some OEM floor mats but not too sure about aftermarket ones.
But so far, they only have the front liners available for sale. I hope the back seat and trunk liner will come soon.Go to brand is Weather Tech.
+1 Ive had the husky in my si since july and they are great just as good as weather tech but a little cheaper. Plus they still have lifetime warranty and im not biased at all ive only used weather tech in the past but didnt feel like spending almost $200 on floor mats.I picked up a set of Husky Liner mats, perfect fit, time will tell how they hold up but they look beautiful. Front and rear set. Then I got the official Honda Cargo tray for the hatchback. I bought on Amazon, Husky part number 98461, ~$125.
