Steens Mountain 2.0 is the insulated layer we file when the shell is already packed. Columbia still sells style 1476671 at $65 and prints 28.0 in / 71.1 cm center back.
The same page names 100% polyester MTR filament fleece, Regular fit, zippered hand pockets, and an adjustable drawcord hem. Weight is not printed on that page, so we do not invent one.
Shortlist reason: a live style number, a printed center-back length, and a current list price on columbia.com.
