Protection Dorsale Norrøna accessories D3O removable Femme Orange Éclaireur – Protection Dorsale

D3O® removable back protector for the skibotn 15L pack and the fjørå 18L pack.D3O® core patented technology is based on non- Newtonian principles.In standard conditions, the polymer chains on a Non- Newtonian fluid flow freely, allowing the material to remain soft and flexible but on impact, they lock together dissipating the impact energy, reducing the force transmitted.This event lasts milliseconds; the polymer then instantly returns to its flexible state.The D3O® patented technology incorporates this Non- Newtonian into other polymers for a rate sensitive solution.
