In 1957 Eddie Bauer created a down-filled undershirt, thus introducing the concept of layering insulation systems to the general public.

The Style 25 Down Undershirt was popular and has since inspired many variations, including Eddie Bauer’s own original Microtherm, introduced in 2011 as part of their acclaimed, pro-tested First Ascent line of mountaineering gear.

The New Centennial Collection
With its new Centennial Collection, Eddie Bauer pays homage to these and other innovations throughout its long history. This not so much a throwback collection, as one that looks forward while acknowledging many decades of field-testing in the Pacific Northwest. (EB’s first store opened in Seattle, WA in 1920. Today the company is headquartered across Lake Washington in Bellevue, WA.)

Microtherm 1000
The Centennial Collection MicroTherm 1000 updates and expands upon the 1957 and 2011 concepts. Instead of an undershirt, it’s a full-blown puffy—a very lightweight, sleek and packable one. It features 1000 fill power RDS down for extraordinary warmth at minimum weight. Many of the Centennial Collection pieces contain down insulation, which Eddie Bauer has been innovating since 1936 when they introduced the Skyliner—generally considered the first quilted down jacket. The new Tech Skyliner Model is the Centennial Collection update of this jacket.
The Microtherm 1000 also refines the signature microchannel quilting of the original Microtherm with discontinuous construction to further enhance the thermal efficiency and to prevent cold spots. Apart from the cozy, enveloping warmth, our favourite feature is the full-range mobility thanks to stretchy side panels. And we always appreciate packability—the jacket packs into its zip chest pocket for easy transport. This is a key feature because it means you’ll always bring your Microtherm 1000, even when you’re not sure the conditions warrant it. Since it takes up so little space in your pack anyway, why not pack it for peace of mind?
