The Evo Compression jacket with D3O armour provides high impact protection in a garment that's flexible and breathable. 

The Padlock connection system ensures the pads stay in place when they're most needed.

D30 TECHNOLOGY:

• D30 technology moves freely in its normal state but locks/hardens on impact, to minimise or prevent injury.
• With strategic D30 pads and panels, vented compression fabrics and mobility patterns, the Evo family stands alone.

• Removable D30 pads in the shoulders, elbows and back. These pads meet CE 1621:1 standards
• Elbow straps ensure that the pads stay in place, both while riding and in the event of an impact.
• The wide neck opening, raised stomach panel, generous underarm cutouts, elbow openings and full front zipper all contribute to comfort while in the riding position, with a full range of motion.
• The full-length zip allows the jacket to be put on and taken off easily.
• The back D30 pocket doubles as a hydration bladder holder and includes a hose routing
• Padlock Connection System:
  • Attaches to your Evo shorts to keep the jacket from riding up, which completely prevents pad migration before and during an impact.
