ColumbiaWomen's White Out Mid Omni-Heat Long Hooded Jacket Coat Puffer (S, Black)

Is this coat warm enough for New York in December?

does this coat have an inside security pocket? and how long is it?

Is this really Columbia brand? I don’t see the logo on chest area in the photo

La chaqueta no trae instrucciones de lavado. Necesito saber cómo se lava!! Gracias por la colaboración!
