2XU Project:X/ X:C1
Project:X/ X:C1 sounds like a science experiment but more than that, it's already proven to give you the biking advantage--scientifically. It has a 20:18 C-Change Membrane that features an opening and closing pore technology and an aerodynamic cut specific to your cycling activity. The moisture transfer release rate of 18,000 keeps you dry and waterproof and wind proof properties prevent the chills. It's almost futuristic.
