Behind the scenes

 * Regarding the design of the vault jumpsuits in Fallout 3, concept artist Adam Adamowicz stated, "Designing, or redesigning the vault suit meant adhering to canon, and updating the textures and tactile feel for the detail we can achieve now in games. I opted for a more durable denim like material, something quintessentially American and, suited to carrying out vault tasks involving heavy machinery and crawling through metal pipes. Overall, the vault suit seems to represent an Everyman/Everywoman uniform of conformity, and a blank canvas for accessorizing once the wearer had escaped into the harsh environment of the wasteland. Preserving the retro 50’s flavor seemed to support this, and I wanted the suit to feel at home in a classic 50’s sci-fi film like Forbidden Planet. The reinforced elbows and knees seemed to introduce a bit of that flair to the otherwise oppressively Orwellian environment."
 * The Art of Fallout 4 included artist statements about the game's vault suit design, including one that noted, "Creating a skintight costume in bright blue and yellow and not having it come across as goofy looking was a considerable design challenge. We achieved this by focusing on an interesting mix of patterns and textures for the high-tech materials and adding details that grounded the design. For the iconic yellow stripe, we went with a metallic gold foil that serves as a heat-dissipation strip and works with the biometric sensors integrated in the suit."
