Bandanna of Stealth

This ordinary bandanna appears to be a normal way of keeping the dust out of one's mouth while traveling, but it has several secrets. 

1/day without any action other than pulling the bandanna over your mouth, you gain the effects of a Disguise Self spell. At the same time you gain proficiency in Stealth and Sleight of Hand while the disguise is active. If you already have either of these proficiencies, then gain +d4 on any skill check involving them.

1/day while the Disguise Self ability is activated, you may use a bonus action so that the next spell you cast during the disguise self duration benefits from Subtle Spell Metamagic.
