Outdoor Fashion Brand

Founded in 2022 and known among riders as “Big G,”
GAINAX creates high-performance apparel for snowboarding and outdoor exploration.

We combine technical functionality with a fashion-driven perspective,
designing pieces that move seamlessly between mountain and city —
where performance meets aesthetic.

Snowboarding has no boundaries — and neither do the mountains.
At GAINAX, we believe snowboard wear should not be limited to the slopes.

Through urban-inspired design and cross-disciplinary influence,
we extend technical outerwear into forests, riverbanks, and everyday life —
where the spirit of riding continues beyond the mountain.

We call this vision “Unbound the Outbound.”
A belief that nature is not just a destination,
but a way of living.
