The Ultimate Riding Jacket?

I like my Rapha winter jersey a lot but it isn't windproof. I think the most recent version had some windproofing added to it? That would make it 531.

Features

• Excellent moisture transfer.
  
• Itch free.
  
• Windproof front and shoulder panels for additional warmth.
  
• Shaped collar for on-the-bike comfort.
  
• Zipped, mesh-lined vents for temperature control.
  
• Improved pocket configuration for flexible storage.
  
  
  

I generally get too hot even in winter when cycling in London so hopefully this will be enough to see me through winter
