This +2 resilient Invisibility chain shirt is itself invisible. Other creatures can't see it at all, allowing you to wear it surreptitiously. Additionally, the armor's invisible composition is quieter and more comfortable than a normal chain shirt. It loses the noisy trait and gains the comfort trait.

Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
ComfortThe armor is so comfortable that you can rest normally while wearing it.
EvocationEffects and magic items with this trait are associated with the evocation school of magic, typically involving energy and elemental forces.
FlexibleThe armor is flexible enough that it doesn't hinder most actions. You don't apply its check penalty to Acrobatics or Athletics checks.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
