SHORT STORY
From alpine traverses to rain-soaked trails, the Beta Pant is your no-compromise waterproof shield when the weather turns.

WHY CLIMBERS LOVE IT
On a misty morning in the Fjords, when Thor shook the mountains with distant thunder, the Beta Pant was forged in the silence between strikes. Lightweight as Loki’s lies and tough as Mjölnir’s blow, it keeps the wild at bay while you walk through clouds and climb above storms. Rain may fall, but in these pants, you walk dry and free—as if kissed by the gods themselves.
