The WindBlock 1.0 Jacket is your essential layer for unpredictable weather. This ultra-light, slim-fitting shell packs down into its own chest pocket with an on-bike storage strap for easy stowage mid-ride, so you can stash it and forget about it—until you need it. The wind-resistant, 4-way stretch fabric is treated with a PFAS-free dirt- and water-resistant finish to help shed light rain and trail spray, and it’s made with bluesign® approved materials for more responsible performance. A stealth under helmet hood and reinforced elbows add coverage and durability when the conditions turn. Whether you're dropping into a breezy descent or caught in a sudden squall, the WindBlock 1.0 is built to shelter you from the chill.
