D3O® Smart Skin provides a low-profile protective layer

Designed for sports applications, D3O® Smart Skin provides a lightweight and low-profile protective layer that can be directly applied to the garment for better comfort, flexibility and a low-profile geometry. It features the British company’s new D3O Aero technology–a lightweight, soft, open-celled PU foam developed predominantly for the sportswear market. Softer and less dense, it’s half the weight of existing D3O materials, while retaining excellent protective properties against impacts.
