The silk in the Ecopossum blend gives it this subtle sheen that photographs beautifully, and it's genuinely warm without that bulky knit feeling. I've worn it on three chilly walks already and keep reaching for it over my heavier sweaters.

I was skeptical about a possum blend, but this sweater is incredibly soft and surprisingly warm without feeling bulky. The light weight makes it perfect for layering under a jacket.

The zip glides so smoothly and the half-zip neckline sits perfectly without gaping. I’ve worn it on chilly walks and it’s light enough to layer under a jacket but the Ecopossum blend keeps me surprisingly toasty.
