Fluff Fest was an independent hardcore punk festival held each July at the Czech town of Rokycany. A significant event for the DIY music scene of Czechia and the punk subculture of Europe, it was associated with movements such as veganism, anarchism, feminism, anti-fascism, and straight edge. It featured international lineups of bands from diverse punk rock genres including hardcore, crust punk, emo, and grindcore, as well as talks and zines. Catering was provided by local animal rights organization Svoboda zvířat.
Fluff originated from Y2K HC Fest, an event organized in August 2000 in Plzeň by Michal Kočan and Tomáš Kadlec. They renamed it for the 2001 edition and moved it to the Rokycany airfield in 2006. Attendance exceeded 3,000 by 2012, when a free side stage called Psych Tent was established outside the paid festival entrance. Organized by Jakub Ďuraško of Stoned to Death Records, the Psych Tent stage has spearheaded the inclusion of more experimental rock and electronic music into the lineup. The last Fluff was held in 2023.
