This is the Furygan Dorsale XP1 back protector made with D3O technology. If you've not seen or played with D3O impact protection at a show, then you need to because it's impressive stuff. On impact, the molecules within lock together to reduce the force put upon them. It's also light and flexible, just what you need in a back protector. The Dorsale XP1 is CE Level II homologated, breathable and able to be tinkered with to get it to fit snuggly. It's priced very competitively, so is well worth a look.
