This may be obvious but I see many wearing too much when walking, particularly when it starts raining.The usual thing that I see is : folk will put their rain jacket on top of the existing layers therefore they have an extra layer and so they sweat (too much).The idea is to put layers on when you stop. If one habitually takes layers off when resting then that one has too many layers on when walking.As for the poncho, they don't work for me.OK on wide groomed trails, a pain on narrow unkempt ones or off trail and no good in the wind. But that is just me...Franco
