The insulating nanoplastic mining suit that seals a Helldiver in his own heat, sweat, and stink.
The frysuit is the nanoplastic suit every Red driller wears in the deep tunnels of Lykos, hot as its name suggests, insulating toe to head so that nothing gets in or out, least of all the heat. Sweat puddles at the heels, and men choose the stink of pissing in the suit over a catheter. Marked with a clan's Sigil, painted blood-red for a Helldiver, its layers melt away in seconds near the drills, as Darrow's nearly does when his foot jams.
A close-fitting nanoplastic suit, rust-red, marked with a clan Sigil on the back and painted deeper blood-red for a Helldiver; sealed with a pop-off lid.
The standard protective mining garment of the Red drillers.
