Naturally Warm

Eiderdown is perhaps the most desirable down in the world. And unlike downs from breeding farms - which invariably come from slaughtering birds - no duck is killed during the down harvest, making it ethical down and a uniquely renewable resource.


Naturally biodegradable, with unrivalled insulation characteristics, this most luxurious down has a unique high density and breathability. Its insulating capacity is so advanced that it adapts to the body's temperature.

Eiderdown will resist the test of time with extraordinary elasticity and resilience; this precious natural fibre is incredibly durable. Containing no feather, it can be compressed repetitively and still recover its initial volume, meaning it never loses its lofting capacity.

Down provides approximately three times the warmth per ounce than even the best synthetics and has a significantly lower carbon footprint.

Waxed Cotton

Our luxurious organic cotton canvas has been weatherproofed the old-fashioned way by Halley Stevensons in Dundee, Scotland - expert wax masters since 1864. Our waxed cotton shells are naturally breathable. The wax adjusts to ambient temperature to be softer/more breathable in warm weather and stiffer/more windproof in cold conditions. Without PFOAs or formaldehyde, our coats outers have a unique appearance and an extreme resistance to the elements. The densely woven cotton is resistant and reliable. The wax finish naturally picks up marks and creases through use, looks better with age and continually adapts to the wearers' personality to create one-of-a-kind pieces.

Our specific wax finish uses all-natural plant-based waxes and oils consisting of a blend of olive oil, rapeseed and castor bean. All components are biodegradable and considered vegan friendly. Olive oil and wax are non-GMO and are natural by-products from the food industry. Rapeseed oil has a low carbon footprint and non-GMO properties. Castor bean originating from India is a resilient crop, pest-resistant, tolerant to drought, and suitable for marginal land cultivation.


Olmsted's high-quality, N°10 metal nickel-free zippers are incredibly robust and custom-made in Switzerland by riri. Founded in 1936 in Mendrisio, the company maintains its production in Switzerland. And remains committed to a manufacturing process based on ethical and sustainable practices.

Our main challenge is to avoid plastic, favouring long-lasting natural materials. Therefore, our most reliable and sturdy hardware is made of durable Nickel-free brass, in a neat black copper finish that blends smoothly with Olmsted's clean aesthetic.
