Montane's Prism jacket will provide the warmth of a fleece with about half the weight. An adjustable wired hood and comprehensive feature set make this a really flexible jacket.

Montane says:

The most versatile piece of insulation in the MONTANE® range, the Prism is an essential piece of mountain clothing whatever the activity. Using 40g PRIMALOFT® insulation throughout ensures that the Prism is warm yet lightweight enough to be worn on the move in cool conditions. Used and abused by Mountain Rescue teams across the UK, the Prism can be worn as a mid-layer within any shell system or alone as an outer jacket in drier weather.

Montane's Prism jacket uses just enough Primaloft filling to generate the insulation value about equivalent to a standard weight fleece - but its only about half the weight, has a highly technical hood that moves with your head and a decent DWR (water resistant) coating on the face fabric. Lots more functionality and lots more performance.

The only thing we think it lacks is an internal chest pocket - but that's a minor gripe.
