Umbrella and raincoat
In our 6 days in Vipiteno areas last June, weather varied quite a lot.
We had days of continuas drizzle (wear Jeans, shirt, a light raincoat or keep an umbrella )
and days of sun, where we also wore shorts.
However, we always kept a light jacket handy for high altitudes, where we also were on snow. A good tracking shoes is very handy.
