ANY of our jackets and coats can have down added to them as an optional extra, as well as the jackets in this section. We only use Pure Goosedown . It is the finest down you can buy. Ours is from Canadian/Italian producers, Thindown, using their revolutionary method of producing. It is always ethically sourced and certificated.Down is a natural, biodegradable, renewable and environmentally friendly source. An alternative to oil-based synthetic materials, whose microfibres, cannot be naturally reintegrated in the ecosystem and accumulate in the environment.
