The Obsidian offers the ultra-light option for extreme weather. Designed as a super packable option with full-length side zippers so you can slip them on quickly over your boots when the weather takes an unexpected turn for the worst.
The Obsidian Trousers pack down incredibly small and weigh next to nothing, so you will barely notice they’re sitting in the bottom of your pack. But when they’re needed, they are extremely waterproof and breathable, just like your traditionally heavier and bulkier work-horse rain layer. Unlike a lot of back-up style rain-wear, the Obsidian was designed with all the important features you still need including an athletic cut and key pockets. These trousers pack down tiny into their own thigh pocket when not in use so they can disappear into the bottom of your pack.
