Wingsuit

When falling, you can expend a reaction to spread your arms and legs to engage a wing suit, preventing you from using your hands, but allowing you to glide. While maintaining a controlled glide, you take no fall damage, and you can move up to 2 feet horizontally for every 1 foot you descend. 

A wingsuit is sewn into any type of light armor, where it is affixed permanently. Other armor types are too heavy for it.
