I bought cheapo and they fit like crap. Got me some Wet Okoles for xmas and they fit like a glove. Tuck in where they are supposed to and form fit like they are the factory seats. And the wet suit material means that its flexible even on cold days as well as breathes on hot days. And they look awesome.
a little pricey but you get what you pay for. mine are 3 years old and a little faded but still look and fit GOOD!
they say not to wash in the washer but the dog ran through the mud and snuck in the open door. GGGGRRRR.
