I dis'd the Escaine when I first saw it. Lexus' line about reducing driver slip versus full leather sounded bogus to me - put better side bolsters on the seats!
But I got over it. In fact, since I expect the Escaine to wear very well, I decided I actually like it, perhaps better than my wife's full leather RX seats. It is cool in the summer and likely warm in the winter (or as close as we get to winter in So. Cal.!). And it does keep yer butt from sliding around...
