Do gas masks function effectively in GTA Online?

In GTA Online, gas masks serve as a cosmetic option rather than a functional piece of equipment with specific protective benefits. While they add to the immersive experience and allow players to customize their characters for a more tactical or militaristic appearance, gas masks do not offer protection against tear gas or other environmental hazards within the game. The primary purpose of gas masks in GTA Online is to complement a player's style and outfit choices, fitting the diverse personalization options available to create unique personas in the virtual world.
