A type of pilot suit from the MuvLuv series.
While there are slight variations between the different nations' suits, the general design remains the same - a skin tight bodysuit with a see-through section on the torso that allows for a full range of movement and deflection of physical attacks, with some metal armor on the upper arms and lower legs, and an interface system around the head to allow for direct retinal projection of the control displays.
The male variants of the suit notably has less of the translucent material than the female variants, which have that segment extend down to the inner thighs.
The suit's chin guard is notably absent in Alternative's anime adaptation.
