I've just bought the PHD Zeta which has worked brilliantly whilst stood round in the cold and rain. I've not yet had the chance to do use it on any winter routes, but if the snow ever comes.......

Anyhow, it's a really well made bit of kit and another option to consider if you're after a belay jacket.

Thoughtful design touches like clip in loops and reflective tags show it's mountaineering pedigree. On the downside, it's a truly ugly piece of kit that should never be worn to the pub!

I wouldn't recommend a true belay jacket for walkers, though, as they're probably too warm for anything other than standing around holding a bit of rope while your mate faffs around climbing.

Montane Solo, TNF Redpoint, Rab Photon, Berghaus Infinity use the lighter weight 60g Primaloft, and more suited to general use.
