The Railroad Gas Mask is a post-apocalyptic protective gear piece with a retro-futuristic design. It features a rounded, bulbous visor made of thick, slightly yellowed glass, providing a wide field of view, mounted on a sturdy, weathered metal frame with visible bolts and seams. The mask includes a reinforced rubber seal around the edges for airtight protection, and a series of filters on either side, made from aged brass and corroded metal, hinting at frequent use in harsh environments. The straps are made from frayed, durable fabric, adjustable with rusted metal buckles. The overall color scheme is muted, with shades of olive green, brown, and metallic tones, accented by scratches and dirt marks that tell tales of survival.
