The latest addition to our iconic Helium range, a bestseller for over ten years! These warm and functional shorts are extremely lightweight and packable. The wind and water-repellent shell combined with the premium 90/10 down insulation is great for any mountain activities, while the full side zips make them easy to put on and take off. Wear them one size up as an outer layer or in regular size under shell pants for extra warmth. We only use responsibly sourced down that's fully traceable through the Track My Down® program. Made from PFC-free recycled polyamide.
