I have a pair of those actually. I used to use them on my road bike before I got clipless pedals for it. Even though they are not laminated they are really thick and seem to be pretty sturdy. I'm still nervous riding fixed on a single layer of any material though. I will have to re-evaluate my strap situation before these Silva/Marinoni straps die which probably won't be too long. I really wish they would stay together they are really awesome. Nice and snug, hold their shape and I almost never have to adjust them because they don't stretch they just stay at the same tension you leave them at... until they die.
