The thermoptics izubachi is referring to were worn by Major Motoko Kusanagi, of Section 9, in Ghost in The Shell. Those had several notable characteristics; they worked better when skintight, and could be defeated by large numbers of particles hitting the surface of the suit (at least, the cheaper ones worn by her adversaries and their vehicles could). Maj. Kusanagi did not, in fact, get nekkid as has been suggested. Rather, she removed outer clothing to reveal a bodysuit composed of thermoptics. The bodysuit included foot slippers and a hood; facial cover was provided by a set of 'curtained goggles.'
