I've always followed the idea of staying dry from the outer storm. I don't let that get me wet by much. What's always been a problem is getting too wet from the inner storm. That's what has always chilled me. Even if I stop and put on more clothing. Without taking off everything wet, being wet, especially at the base layer, I would chill. With the coming of Patagonia's Capliene, used in conjuction with pit zip outer shells, and/or fast drying insulation layers, I've always stayed dry enough before I'd chill using them. I've used wool for many years. Still do for some uses. But, even with super fast drying insulation layers and excellent venting shells, wool base layers still chills me where my Capliene base layers don't. I've used this stuff in heavy rain, working hard, and had it dry amazingly fast just from my body heat. Wool won't do that. I've used their super fast drying Regulator Fleece and found it much better as an insulating layer as well. E
