William aka WhereToWilliewrote a review of Arc'teryx Cerium LT Hooded Down Jacket - Men's on April 9, 2018
Familiarity: I've put it through the wringer
Fit: True to size
Packs down to nearly nothing, it's 10oz profile means you'll always throw it in your bag. The loft of this jacket is where it really shines, I can't imagine something being lighter than this while maintaining it's loft. If anything, throw a wind jacket / shell over top and you'll have a full winter jacket that packs to grapefruit size.
