Depends on your expectations. - Breathable clothing only stays breathable in a downpour if the face fabric stays dry, e.g. the DWR is not overwhelmed - The clothing is usually a pretty active cut, compared to galoshes and ponchos. This tends to allow water in at the neck, cuffs, and waist over time. - The breathability is driven by positive vapor pressure, so it will get humid inside the jacket.
