Battle Armor

Battle Armor called Saiyan (Battle) Armor by the Earthlings before the Namek Saga, is a standard-issue combat attire currently mandatory throughout the Planet Trade Organization. 
Battle Armors are made of an unknown material, which is said to be stretchy, yet very durable. Even Saiyans in their Great Ape form are able to wear their armor without having any size issues. It is said by Malaka that his Battle Armor saved Vegeta from being crushed to death when he was fallen on by Great Ape Gohan, a sign of the armor's durability. However, they are known to shatter when dealt enough damage, showing that they are indeed hard and solid. Vegeta once stated that Battle Armor is the Saiyans' formal attire. Also, he once remarked "one size fits all.
The most commonly seen ones have dual shoulder guards and some form of skirt armor or crotch guard. Matching boots (often white in color, but others do exist) are standard issue, as is a pair of white gloves or fingerless wrist guards. Standard armor has large shoulder plates, but some simply have reinforced shoulder straps. Many also have skirt armor or plate shielding the crotch. Most Saiyans wrap their tails around the armor's waist, appearing as if they have a furry belt. Some armors feature capes, either pinned to the shoulder guards such as that of King Vegeta and King Cold, or extending from the back of the lower half of the armor such as Zarbon has.
