PU rainwear or shell — what's the difference?

PU rainwear and shell clothing can both be good choices for Nordic weather, but they don't quite solve the same problem.

PU rainwear ("galon" in Swedish) is made for really wet situations. It stands up well to rain, slush, puddles and damp sand. For kids who sit a long time in wet grass, jump in puddles or have a day of steady rain at preschool, PU rainwear can be very practical. It's also easy to rinse off when muddy.

The downside is that PU rainwear barely breathes. That means moisture and warmth from the body can stay on the inside. A child who runs a lot can get sweaty, and once the activity slows, things can start to feel cold. The layers underneath matter: not too much, not too tight, and ideally wool or fleece depending on temperature.

Shell garments work differently. They're often made with a membrane or coating designed to keep rain out while letting some moisture escape from the inside. That makes them more flexible for active play, shifting weather and layering. On the other hand, they depend more on good fit, seams, care and DWR re-treatment to perform well over time.
