Lattice Training have released the trailer for their debut feature film 'World Class.' The film documents Aidan Roberts' achievements over the past year; from swift hard repeats of some of the UK's hardest boulder problems, to climbing his own testpieces including what is potentially the country's hardest problem: Superpower (f8C).

World Class interviews some of the UK's top boulderers including Dan Varian and Jack Palmieri, who both sing Aidan's praises. Jack argues that through Aidan's most active 6-8 week period this year, he took UK bouldering to a new level.

The full film will be released on 22nd December and we'll be posting it up on site.
