The North Face Redpoint Optimus

This duvet jacket weighs 660g; Primaloft insulation; packs into its own pocket; very comfy cuffs; large hip pockets plus chest pocket; hood fit is excellent. But only warm enough for mild winter use; hood cannot be removed or rolled down.

Verdict: Buy it if you want a low-priced warm layer for mild winter weather or a back-up garment for all year round.
