Mark 90 Flight Pack

 is a Glider in Fortnite: Battle Royale that could be obtained at Level 98 of the Chapter 2: Season 4 Battle Pass. It is part of the Iron Man Set. It can only be used with Tony Stark as it is "coded to only work for him".

Cosmetic Review
The flight pack is covered in red armor, shaped like wings with Nanotech on the inside. Boosters can be found on the bottom of the wings.

The repulsors on the hands and feet of the Tony Stark Outfit hover using boosters, as shown in the image for the Glider.
