Mammoth South Park When The Week Opened Up

Mammoth Unbound’s South Park sat huge under California spring light, rails polished by six days of laps and jumps carrying more speed than most finalists expected. Felix Klein arrived at SuperUnknown 21 with a style built far from that exact terrain: Snow Park memories from Wānaka, British team starts, indoor and dryslope habits, and Boom Club filming energy. By the end of the week, Level 1 listed him as the men’s SuperUnknown 21 winner. Freeskier described him as composed through the session, finding his own creativity inside a park that could easily swallow a rider’s identity.

Snow Park Nights In Wānaka

Klein’s own biography gives the cleanest early scene. He grew up in Wānaka, New Zealand, and traced his skiing back to Snow Park in 2008, when his mother would pick him up after school for night skiing with his brother and friends. That detail matters because Snow Park was not just a local hill. It was one of the key Southern Hemisphere freestyle zones, a place where jumps, rails, pipe features, and international riders shaped young skiers before European or North American contests entered the picture. Klein says he began training around age twelve with Nico and Miguel Porteous, tying his early progression directly to two skiers who later became central to New Zealand freeskiing.

Cirencester And The British Team Turn

In 2015, Klein’s family moved to Cirencester, England. His skiing then shifted into the British system, where he competed with the national team while carrying a New Zealand park background. FIS lists him as a Great Britain freestyle skier with FIS Code 2532867 and a birth year of 2000. GB Snowsport later named him to the 2022-23 British Freestyle Ski and Snowboard B Squad for freeski slopestyle and big air, alongside Dylan Boyes, Mason Ferebee, Jasper Klein, and Justin Taylor-Tipton. That selection placed him inside a British freeski group led publicly by athletes such as James Woods, Kirsty Muir, Katie Summerhayes, Izzy Atkin, Chris McCormick, and Tom Greenway.

Davos, Corvatsch, Leysin, Stubai

Klein’s official FIS record is compact but useful. The listed results include European Cup and European Cup Premium starts in slopestyle and big air, with stops at Leysin, Corvatsch, Davos, and Stubai. In February 2019, InTheSnow reported that he finished ninth in a Davos Europa Cup big air, ahead of Justin Taylor-Tipton and Jasper Klein in the British men’s results. FIS later recorded a seventh-place European Cup Premium slopestyle finish at Stubai on April 22, 2022. Those results do not make him a World Cup podium athlete, but they give the competitive base behind the later media profile: he had already spent years inside judged park and big-air environments before the creative lane took over.

Saisho With The Porteous Brothers

Saisho, released through Red Bull Media House in 2023, gave Klein one of his clearest film credits. The short follows Miguel Porteous, Nico Porteous, and Felix Klein from Tokyo to Hokkaido as they experience Japan for the first time. Apple TV lists the same documentary with a 23-minute runtime and credits the three skiers as on-screen subjects. The project is important because it links Klein’s past and present. He trained with the Porteous brothers as a kid in Wānaka, then reappeared beside them years later in a travel-based freestyle film. The setting moved from structured park laps to Tokyo energy, Hokkaido snow, and a looser idea of what a ski trip can show.

Boom Club Before The Edit Starts

Klein’s strongest current identity runs through Boom Club. The collective describes itself as a production and events group built around skiing, UK garage, bassline, fisheye filming, movie nights, rail jams, afterparties, clothing, and resident skiers. Its founders are listed as Tom Greenway, Felix Klein, and Nico Porteous. That mix explains why Klein’s profile does not fit a normal competition biography. Boom Club is part crew, part event platform, part video label, part social code. It gives British and international skiers a place to connect through music, style, rail events, edits, and a less polished side of freeski culture.

Höhenstraße Speedrun And The Austria Rail Mood

Freeskier’s 2024 coverage of Höhenstraße Speedrun placed Klein inside one of Boom Club’s clearest recent edits. The article described the crew taking on Austria with repeated Blue Tomato rails, Gavin Rudy behind the lens, and a lineup including Tom Greenway, Felix Klein, Ben Barclay, Ryan Stevenson, Jasper Klein, Tenra Katsuno, Dane Kirk, Billy Cockrell, Gavin Rudy, Harris Booth, Nico Porteous, and Miguel Porteous. The terrain language here is different from FIS slopestyle. It is faster, looser, and more crew-driven: rail hits, park transfers, fisheye angles, music timing, and the feeling that the clip matters because the group knows exactly why it is funny, risky, or clean.

SuperUnknown 21 And The Mammoth Vote

SuperUnknown 21 became Klein’s strongest public result in ski culture. Freeskier reported that the 2024 finalist lineup headed to Mammoth Mountain for six days at Mammoth Unbound, with riders selected from hundreds of video submissions. Level 1’s official SuperUnknown history lists Shiori Takahashi and Felix Klein as the 2024 winners. Freeskier’s recap adds the texture: the vote was close, the finalist group was deep, and Klein’s composure stood out through the week. His own quote from the event pointed to nervous early days, confidence building through the session, new lines shaped to each rider’s style, and a direct shoutout to Boom Club.

Style Between Wānaka And Britain

Klein’s skiing reads like a hybrid of park training and crew-based filming. The FIS side explains the slopestyle habits: speed management, rail approach, switch takeoffs, grab timing, corked rotations, and full-run awareness. The Boom Club and SuperUnknown footage context points toward a freer layer: side-hit creativity, rail choices, transfers, butters, low-pressure landings, and tricks held for style rather than only score. His movement is less about one signature trick than about composure. That word appears in Freeskier’s SuperUnknown recap for a reason. Klein can enter a large park build without looking rushed, which is difficult when the setup is bigger than the terrain a rider normally trains on.

The Profile Still Has Room To Build

Klein earns a 3/5 importance rating because his public record has moved beyond a basic emerging profile. He has FIS and British squad history, a Red Bull film credit, Boom Club cofounder status, and a Level 1 SuperUnknown 21 men’s title. He does not yet have a World Cup podium, X Games medal, Olympic start, or long individual film résumé, so a higher rating would overstate the record. The current markers are concrete enough: Boom Club edits, SuperUnknown visibility, Japan footage with the Porteous brothers, and a creative path that keeps shifting from judged park skiing toward filming, events, and freer travel projects.
