I have an Arc'Teryx Softshell hoody and it is THE nicest bit of kit I have. Used it for commuting all year last year – with a shell over the top when necessary. Fits so well. I can't actually remember the name of it – I thought it might be this one (new version) but I paid £100 in the sale, down from £140 nearly 2 years ago. I'll keep looking – can't recommend it enough. A mate who is a mountain guide has had one for 5 years – it shows, but its still going and there's a reason why you won't want to replace it.
Also looks ace down the pub…
EDIT: This is it. Got mine from Tiso.
