Protecting myself
A brilliant tip given to us by mountain guides and Alpine guides is to take an umbrella with you. Big enough to protect you and your backpack.
Put a waterproof jacket and pants at the top of your bag so you can get them out easily in case of a quick shower. I say "quick shower" because the most breathable waterproof products eventually create condensation and you will be wet from the inside if you hike for too long wearing them!
Putting a pair of gaiters on over your boots guarantees dry feet.
And if you want to stay on the move without covering up, I recommend the Merino wool T-shirt because it stays warm even when wet!
