Because We Need Male Touch!
More seriously, it does have some cost. A full night-ops outfit, plus a cattle prod and rare earth. Also uh, I guess you have to lose a Superslave in battle or something? IDK, I haven't tried the superhero stuff. The Batglad armor does seem pretty nice though, almost as good as Warrior but on a male soldier. I got a giggle about the rear armor being particularly strong, guess it's the durathread cape
Edit: The armors you get for respecting men, Operator and GI and such, have a lot less armor than Batglad for the record. I think they get some bonuses to carry weight and weapon skills though. They make decent mortar teams or even snipers (except at night), but they're always going to be fragile. Almost as fragile as peasants, but 3X as expensive (but usually stronger). But then, Peasants get the excellent and cheap Militia armor that boosts experience gain while providing a modicum of protection...
Unrelated: I've been enjoying the "pointy sticks" as early javelins (particularly underwater), and even the bamboo rods as early spears, but Pikes are really good at defeating armor for how early you can get them (requires Smithing, Primitive Weapons and Contacts: Merchants, then Tools & Blades). Range of 3, too!
65% armor effectiveness, only 10% penalty for one-handing, and deals 35+.4Strength+.25Throwing (I tend to read such things as "around 35+40+25 for a veteran gal", even though I don't usually train throwing so much). I don't know how good Stabbing is as a damage type though. Oh and it's ranged with 125% accuracy, so it'll basically always hit outside of melee. The big downside is 24 TU cost.
