When it comes to musty smells on a nylon/cashmere/down-filled coat, there are a number of interrelated issues
1. Oil-based and water-based stains
The vast majority of stains fall into one of two categories: oil-based stains and water-based stains.
Oil-based stains are stains such as butter, salad dressing, steak juice, body oil, creams and lotions.
To remove an oil-based stain, the garment must be pre-spotted/flushed with steam and completely hang dried. Prior to being dry cleaned.
Dry cleaning should emulsify or dissolve the residue of the oil or grease stain that hasn’t been flushed out with steam during pre-spotting.
About 10% of all visible stains a cleaner encounters are oil-based stains.
Water-based stains are stains such as soda, juice, champagne and perspiration
To remove a water- based stain, the garment must be pre-spotted/ flushed with steam and completely hang dried, and/or wet cleaned and completely hang dried. Prior to being dry cleaned.
About 90% of all visible stains a cleaner encounters are water-based stains.
And here’s where the problem arises.
You can dry clean a garment with a water-based stain such as perspiration as many times as you wish. More often than not, that stain won’t “move” with dry cleaning alone.
Conversely, you can wet clean a garment with a oil-based stain as many times as you wish. More often than not, that stain won’t “move” with wet cleaning alone.
You've already dry cleaned the coat. So, in all probability, any smells related to body oils have been removed.
That leaves WATER-BASED STAINS, most likely PERSPIRATION. And, in all probability, the only way to remove the mustiness is through WET CLEANING.Learn more here

2. High quality down should never be dry cleaned
When you buy a garment that contains down, you are primarily paying for the outer fabric, construction and the quality of the fill – the down.
The quality of the down is largely determined by the fill power or loft of the down (i.e., the ability of down to puff up, capture pockets of air and have that air heated by body heat....that's how down keeps you warm).
Fill power is, in turn, largely determined by the size of the down clusters or individual pieces of down (there could be tens of thousands of down clusters in that coat).
Each down cluster has thousands of filaments (think: fibers) radiating out in all directions from a center point (think: head of a pin). Each of these filaments are coated with minute particles of oil. The oil on the filaments give the filaments their structure or “body”. And “body” gives down, amongst other things, it’s wonderful ability to loft after it’s been compressed and released.
And what is the primary function of a dry cleaning solvent or fluid?
It’s to dissolve or emulsify greases and oils
Fact is, water and detergents don’t come close to matching the oil and grease dissolving properties of all relatively aggressive dry cleaning solvents.
So now that you’ve dry cleaned your down coat, what happens to the oil particles on the filaments of each down cluster?
The oil dissolves.
And what happens when the oil dissolves?
The down clusters loose their structure or “body” – their ability to loft – and your down coat looses it’s functional and monetary value.
In other words, you're paying the dry cleaner to knowingly destroy the down in your down coat!

3. Fabreze is ineffective (Read: useless)
Fabreze masks the odor. TEMPORARILY.
Then, as the masking "power" of the product dissipates, you're back to square one. Furthermore, Fabreeze contains some nasty chemicals not even listed as ingredients.
You need to eliminate the problem, not cover it up temporarily.
4. Freezing is ineffective (Read: useless)
See (3) aboveRECOMMENDATION
You should find a wet cleaner who can handle all the elements of the coat (nylon, cashmere, down).Edited by stubloom - 2/4/17 at 7:00am
