An advanced, patented polymer, CE-rated D3O® impact protectors are the latest advancement in protective armor. D3O® impact protectors utilize intelligent molecules that lock together on impact. Because of this, the impact protector can be made thinner and lighter, making a jacket more comfortable and easier to wear. However, this decreased size does not come at the expense of impact protection. D30® CE-rated back pad. Compatible with Icon women's motorcycle gear. Sold individually.
