A very light umbrella (200g) and really small. At the bottom of a bag, it is forgotten. It folds out and folds without having to force, although it is not automatic. I used it in windy weather without turns.
Given its size, it is of course an umbrella one person. If you use it at 2, you will wet shoulders.
Only downside: the flat handle is T-shaped rather unpleasant to hold in hand
