Very good reply there Andy, but there are some factual errors.
TM offers his suit in 1.5 and 2 mm (maybe still 1 mm too, but have not seen that in a long time). However, only the 2 mm is acrylic capped (makes it glossier).
ATA might be said to have linage, and it's not untrue, but its origins are of ROTJ armour with an ANH helmet. The armour has then over many years been reworked to look more like ANH by people other than ATA, although I'm sure he has made his own contributions too. ATA comes from recasting CAP (which was permitted), who in turn recast TE. What ATA had to do was add his own knee plate and some other bits.
