In reply to UKC Gear:
Yesterday was a baltic day in North Yorkshire. Intermittent mist, very very windy. Very hard to stay warm whilst on the boulders. I'm quite keen to get a new down jacket of some description, but need something that is easy to get on and off between attempts on problems and, more importantly, is very very warm!
It's a little unclear from the review whether Rob used this exclusively as his warm layer, with no other jacket, and whether he managed to get out in any particularly full on conditions. Rob, would a Filoment type jacket make an aqedquate substitute to the traditional enormous duvet jacket for bouldering on a very very cold and windy day?
