Franmaryp, I did Le Puy to Pamplona starting in early spring 2010, then, this year, Pamplona-Santiago and beyond, starting in late winter. Obviously, I encountered much snow, mud, rain and sleet, although I also enjoyed many radiant days. If I were to start all over, with the knowledge I have now, I would have a zipped
Altus to keep me and my pack dry and settle for wet feet or, at least, wet trouser bottoms. I should add that no other poncho but the
Altus will do, since most are not stable in wind. Worse, my expensive Exped was not at all waterproof, my expensive Sea to Summit sil-nylon let in water under wind-pressure and gave my passport and credencial a soak. (No, it was not condensation.)
Underneath, I would have several layers of quick-drying garments, nothing with buttons or of heavy fabric, and just one fleece jumper. Why carry clothes in cold weather when you can wear them?
For my hands, I'd have mits because they are easy to slip on and off when the fingers are cold and wet. I found my snow-gloves to be a problem and ditched them. If using trekking poles, the hands can be tucked back under the sleeves of an
Altus - very handy.
A zipped
Altus is much easier to get on, important if you are on your own or if the wind is howling. In doubtful weather, you can always put it on well in advance without over-heating, since the zip allows for ventilation.
On this forum, we keep saying
Altus. Gets boring, but I wish I'd listened the first time.
Franmaryp, a cold Camino is just another great Camino, and you will love it, I'm sure.
Buen Camino
Rob
