Rainbow Cloudcruiser

Rainbow Cloudcruiser is an Glider in Fortnite: Battle Royale, that can be unlocked by logging in anytime from August 5th at 10 AM ET to August 9th at 10 AM ET while owning August 2021 Fortnite Crew Pack. It was released in Chapter 2: Season 7.

Trivia

 * Technically, it only required you to own Summer Skye, rather than the monthly Crew Pack, to unlock Rainbow Cloudcruiser, meaning that you still could have got the Umbrella even if your subscription had expired earlier that month.
