The Borderlines have less back story, that's how creativity works sometimes. Mathieu wanted to make some simple ledges quickly. He decided to roughly shape 6 hoping that at least 4 would turn out. As it happened, all six shapes hit the goal: simple and fundamentally functional.
Beyond the simplicity of the shapes, what makes these new shapes interesting to climb on is their volume: how much they push out of the wall or force you to reach around them. Squeeze? Pinch? Wrap? Hug? The concaves and convexes of Golden Leaves will challenge grip and position with gentle intensity Hop? Catch? Smear? Hook? Borderlines have you covered.
