all servant's equipement are made of mana. it's why any servant could wear normal gears and make up servant's stuff in one second..Additionnally, they are made of mana too themself, that's why.

The part of Saber is special in a sense that his body is not made of prana like other servants but she has a physical body, which is why she can't pass uncorporeal. However, they keep the gear stuff and some powers like it.Because of his special nature, even some common things among servant count as abilities.
