This fleece is excellent for mountaineering,climbing,skiing, you name it it does it well. the arm pocket is the perfect size for a full size silva compass or a lift pass, the polartech fabric is hard wearing and doesn't bobble like some other fabrics. combined with a rab vapour rise top it creates an exceptionally warm and cosy combo. The fleece really cuts down on windchill and the hood is a godsend, although its a tough job to get over a helmet (it fits underneath one perfectly though. The hood also has a tendency to blow up your head in strong winds as it isn't stowable which is one drawback. The two upper chest pockets are not the most useful because it's quite hard to get items out when they are in,however i have noticed a leatherman fits well inside them. The colour is very easy on the eye, the contrast between the zips and the material makes finding the pockets in low light, or at a glance a very easy affair. The high collar is a very effective seal and keeps the heat in even when you are moving around lots.
