Sorry, but that is wrong! There has to be an article to introduce the "umbrella and coat" object. In English, we cannot say "They bring umbrella." For singular objects, there has to be an article, "a", "an" or "the". It should be "They bring an umbrella" (one umbrella), "They bring the umbrella" (one specific umbrella; or if umbrella is pluralized, several specific umbrellas) or 'They bring umbrellas" (multiple umbrellas).
