100% polyester. Octa fabric. In-built belt. Mesh lined. Two front pockets. One integrated pocket with zippered closure. Two inseam air vents with zippered closure. Waterproof. Regular fit. If youre into flailing about on cliff faces, conquering peaks and other equally-high-octane extracurricular activities, wed like to introduce you to these 2L Octa Pants from Snow Peak. Theyve been concocted from some hard-wearing polyester rammed with what Snow Peak like to called octa tech, which, alongside being tough, is water-repellent too. And thanks to the zero-frills design, you wont look like a wally during a post-ramble pint either.
