How it works

He went outside without putting on a jacket. 「ないで」 describes the circumstances of the main action.

Add 「で」 to the verb’s ない form: 着ない→着ないで. Do not add another ない.

Both parts usually refer to the same person: the person who did not put on a jacket is also the one who went outside.

Even for a past event, the first part uses 「ないで」. The second part expresses the past tense.

In the first example, 「ないで」 describes not wearing a jacket; 「ので」 links the reason to the result of feeling cold.
