Unknown Anatomy Alien Skull Hoodie

Human on one side. Something else on the other.

The Unknown Anatomy Alien Skull T-Shirt features a striking split portrait combining an alien face with a human skull — a dark NULTERRA interpretation of what might exist beneath the surface.

Finished with the NULTERRA NOT OF EARTH identity, the design blends UFO culture, sci-fi and darker graphic art while keeping a clean, wearable look.

Made for UFO enthusiasts, alien believers and anyone drawn to the unexplained.

Find your fit:

Before choosing a size, compare these measurements with a T-Shirt you already own that fits comfortably.

Lay your T-Shirt flat without stretching:

• Length: Measure from the highest point of the shoulder, beside the collar, down to the bottom hem.

• Width: Measure straight across the front, just below the armpits. This is the flat garment width, not your chest circumference.
