Which is warmer, the Down Sweater or the Atom Hoody?

Which handles rain better?

The Atom Hoody. Synthetic Coreloft keeps most of its warmth when damp, while wet down collapses and the Down Sweater loses loft. Neither is a rain shell.

Which packs smaller for travel?

The Down Sweater. It stuffs into its interior chest pocket and clips to a pack. The Atom compresses well but has no stuffsack.

How do the fits compare?

The Atom Hoody is fitted; the Down Sweater is regular and reviewers say it runs looser than earlier versions, with non-elastic cuffs.
