Since all leather garment is dyed, it may loose some colour in cleaning, but our process unsures that it is kept to a minimum and can generally be restored in finishing the Elite process. As part of the finishing process the garments are treated with Scotchguard or equivalent silicone product, whilst this will not 'waterproof' the item it will help to protect against soiling. New garments can be Scotchguard without them having to be cleaned.
