I've tried various types of universal seat covers in previous vehicles. Cotton twill covers and nylon covers both looked nice, but had disadvantages when it came to fitting. Mainly, I just couldn't get them to fit the way I wanted. My next choice was neoprene and the Hatchie Bottom Neoprene Universal Fit Seat Covers were the perfect price and pattern to match the decor of my newest truck.
Neoprene covers fit your seat the same way a wetsuit fits you. They also provide a waterproof barrier that will keep your seat protected from wet waders, wet dogs and the occasional dropped soda. The other advantage of neoprene is its natural insulating properties. During the hot summer months, the covers stay cooler so you're not sticking to the seats. In winter, they keep your seats warmer - a very nice side benefit.
After wrestling with nylon covers in my last truck, all Velcro® and strings, the simple zippered design of the Hatchie Bottom's was a welcome surprise. The seat configuration of my truck called for the bucket seat style with built-in seatbelts, and they fit perfectly.
To install them, it was a simple process of sliding the lower piece over the seat and pushing the excess material between the seat and seatback. The upper portion of the cover drapes over the seatback like a jacket and you just zip it up on the outside. Since the position of built-in seatbelts is fairly standard, the cut-outs for the built-in seatbelts should match up perfectly with your seat design. There are straps on the bottom to adjust the position and keep the cover tight to the seat. And it will stay tight to the seat. The covers smooth out the contours of your seat, giving them a flat appearance, when you're not sitting in them. Once you climb in, however, the neoprene material will stretch to your body and you'll feel all the contours of your seat again.
My only problem with the covers was the zipper wanting to come down, but that was easily fixed with a small stick pin to hold the zipper up. Cut-outs for arm rests would also have been nice, but that's a limit to universal fit covers.
Of all the seat covers I've tried, these are the type I'd recommend to anyone - and they come in styles that don't involve camo as well.
