To answer a few questions about the seat covers now that I've put a few miles on them. The seat coolers still work. However, they are a bit diminished. But I've had a chance to use them and I can still feel them especially on high. The seat covers are 500D Cordura so they are slightly thinner and lighter than the usual 1000D that most packs and other tactical nylon items are made from.
Installation was pretty straight forward. The covers on the front seat bottoms were a little challenging routing the securing straps underneath. That's due to the wire harnesses and whatnot that are in the way. They fit quite well and do what I want them to and that is protect the seats.
The MOLLE webbing and velcro were custom and did not come that way. Mine are Multicam Arid. These covers can be had in just about any camo pattern or solid color. I opted for the Arid just to be different.
I hope that answers most of the questions but feel free to ask if there are anymore questions pertaining to these seat covers.
