Our lightest, most packable 3-layer hardshell for gravel bikepacking. This durable, breathable jacket is wind- and waterproof. We’ve collaborated with ASSOS, the innovative Swiss cycling brand, to create a bike-focused fit. The longer back prevents the jacket from riding up. Ergonomically shaped sleeves guarantee an unrestricted on-bike fit, and a helmet-compatible hood won’t hinder views. Pertex® Shield 3-layer fabric keeps you dry, while a high collar offers extra rain protection. This super-light jacket packs small into its stow bag, perfect for hikes, fast-paced rides and multi-day trips. You won’t want to leave home without the ASSOS x Mammut HS Hooded Jacket.
