"Hummingbird series armor uses Shotlite's "Solid Air" technology to create incredibly light armor pieces with high physical and thermal resilience."
The Shotlite Hummingbird armor set is a very nice set to have if you want to move fast and have high thermal defense. Though be warned that the chemical defense is a major flaw in this set, just like any armor that isn't Graphene or Medusa.
Though for those who want a speed build, this is the one of two Shotlite gloves (and one of the two gloves in the entire game) to give a movement boost. Another is the Dragonfly gloves which also give the same 1% movement boost as Shotlight Hummingbird G1.
