Hi. I was wondering if anybody who has done a winter camino can offer me advice on clothing. I'm sure this may have been asked before but I cant find specific information. I'm planning to walk the Frances next month. I have merino tops and I own a Patagonia Nano puff. I'm trying to keep the back pack weight down and I was wondering if the merino layers with the Nano puff on top merino buff, beanie and gloves would be enough to keep me warm and comfortable while walking. I also have a windproof and waterproof hard shell which could go on top of the puff if needed. Thanks for any advice.
