In reply to 09packhamg:
Usually take a gore-tex running waterproof rather than hardshell, as well as a spare thermal top, gloves, first aid kit, space blanket, map, compass, whistle, food, water etc. Potentially waterproof bottoms too if the mountain forecast was seriously shabby.
Assuming you’re going high (e.g. 2,000m+), FRA mandatory kit is probably not a bad starting point for single days out running in the alps, even in August when the forecast is good.
Either way, have a great, and safe, time.
