The extreme fluffy vest above reminds me of bird feathers. Such extreme fluffiness is rare but there is still a host of fluffy variants to be seen amongst Copenhagen's cyclists.
These vests have been very popular during fall and early spring.
Here an elegant double layered variant with matching fluffy faux fur linings.
There are also many skin and (faux) fur jackets in the streets.
And of course the real fluffy furry deal for those snowy frosty mornings.
