The F-One Trigger Brainchild is a big air kite that is both powerful and accessible. Designed by Ralf Grösel and built at the Brainchild factory, it delivers higher jumps, longer hangtime, lighter steering pressure and better comfort and control across the whole wind range.
The biggest change is a completely new canopy in the softer material first used on the Bandit Brainchild. It makes the kite more forgiving, adds a much better second lift and gives a longer, more controlled descent, so landings are noticeably smoother.
Intermediate to expert riders who want to boost as high as possible and hang there, with a kite that stays easy to control powered or fully depowered.
