Aerial expansion

This mod adds leggings, that can be used to get creative like flight.
Why leggings: there are aren’t that much of them around, and this way you no longer need to use up the chest plate slot for a jet-pack.

All of them are tiered, and powered by Zephirian Aerothenium (not RF/FE). Also equipped with a boost function that can be used with elytras (instead of fireworks). It can be activated with a hotkey, or by sprinting.
it has a neat animation when turned on.

 
Requires Thermal foundation to be installed.
