Wingwear

From Princes of the Apocalypse, page 223.

Description
Wondrous item, uncommon (requires attunement).

This snug uniform has symbols of air stitched into it and leathery flaps that stretch along the arms, waist, and legs to create wings for gliding. A suit of wingwear has 3 charges. While you wear the suit, you can use a bonus action and expend 1 charge to gain a flying speed of 30 feet until you land. At the end of each of your turns, your altitude drops by 5 feet. Your altitude drops instantly to 0 feet at the end of your turn if you didn't fly at least 30 feet horizontally on that turn. When your altitude drops to 0 feet, you land (or fall), and you must expend another charge to use the suit again.

The suit regains all of its expended charges after spending at least 1 hour in an elemental air node.
