For warmth, down is hard to beat. But many insulated pieces have two drawbacks: water-resistance and packability. Not so with the Cho Oyu. It's an ultralight piece with a DWR treatment that makes the shell and the down exceptionally moisture resistant, so it holds warmth in damp conditions. When space in your alpine rig is at a premium, it can be compacted and stuffed into its integrated stow pocket.
