Ultralight rain shells are excellent, highly packable layers designed for weight-conscious hikers and runners who need emergency protection. While they sacrifice some durability and breathability compared to heavier, traditional hardshells, they are highly effective for their intended purpose of dealing with intermittent rain. For the best performance and ventilation, consider models that feature 3-layer construction and pit zips.
