Raid Suit

Raid Suits are special, technologically-enhanced outfits designed for combat. They are developed and exclusively utilized by the Vinsmoke Family and their army, Germa 66.

Design
When not in use, raid suits are contained inside dark-colored cylindrical canisters, marked with light-colored personal symbols ("J" for Judge, "0" for Reiju, "1" for Ichiji, "2" for Niji, and "4" for Yonji). In order to put the suit on, the wearer clicks a button on the canister, causing it to rotate and release the material of the suit; this material remembers the shape of its wearer, allowing it to quickly wrap around the wearer's body and form the complete suit around them.

For male wearers, raid suits typically comprise a set of outer clothes, a pair of gauntlets, and jet-propelled boots. For female wearers, the only difference is that a short dress replaces the outer clothes worn by the men.

All members of Germa 66 are equipped with a raid suit. However, the color-coded raid suits worn by Germa's commanders are significantly more stylized and individualized than those worn by their soldiers. In particular, each Vinsmoke commander wears a long cloak with their raid suit, with the siblings' cloaks all bearing references to both their designated number and their unique abilities.

Abilities and Powers
Raid suits allows their wearer to hover in midair, jump large distances, and boost their kicking power. The suits' gauntlets have also been shown to contain some kind of mechanism for firing powerful shots.

The suits are also completely resistant to fire, thereby allowing the wearer to withstand fire-based attacks without difficulty.

Trivia

 * Germa 66's raid suits were most likely inspired by the outfits worn by the protagonists in the television franchise, Super Sentai.
 * Ironically, while the raid suits are impervious to fire, Sanji is able to ignite himself, further showing his divergence from his family.
