EXTREMELY LIGHTWEIGHT AND COMPACT
When you need protection from wind, cold, or rain, the best jacket is the one you have with you. So we made this one impossibly small and lightweight. And we made it windproof, water repellent, and breathable. And we made it fit just right—close to body without binding. And naturally we gave it that unmistakable Castelli style.

• ForceField fabric for lightweight, breathable wind and rain protection
• Mesh-lined collar
• Expansion vent on back for breathability
