Appearance
The Gas Mask is a full-face black mask with a series of straps securing it to the wearer's head. Both the lenses and a thin stripe on the front filter change to match the color of the wearer's Ink, and unlike most modern military-grade gas masks, it has two side filters instead of one.
Splatoon
Abilities
The Gas Mask comes with Tenacity as a main ability, which, being exclusive to the main slot of Headgear, prevents the wearer from also having Comeback, Last-Ditch Effort, or Opening Gambit. As a 3-star item, the Gas Mask has three additional slots for secondary abilities. Since it is made by the Forge brand, it has a higher chance of rolling Special Duration Up and a lower chance of rolling Ink Saver (Sub) to fill its secondary ability slots.
