I tried going pretty general with the first one but my personal is between 0 to -5 I wear a coat -5 to -10 consider gloves -10 to -15 wear gloves -15 to -20 wear heavy gloves -20 to -30 wear glasses and a buff/mask -30 to -40 add glove liners and question why I live in a place that gets this cold Haven’t gone below -40 but I imagine it’s just complaining
