It can get cold in the mountains, & cosy evenings around the campfire can sometimes be chillier than expected. Better pack your Mens Castle Rock Fleece from Jack Wolfskin, just in case. This jacket gives you instant warmth. The tried-&-tested fleece provides effective insulation, & has an extra soft reverse side for superb next-to-skin comfort. In cold, wet weather, use the system zip to team it with a waterproof outer jacket.
