If you’re anything like me—the kind of person who refuses to be cold, even in the depths of winter—then you’ll know that layering is crucial. As I write this, the temperature outside has hit zero, and my resolve to dress warm has only sharpened. My not-so-secret secret for staying warm while still looking polished? COS’s exceptional range of merino wool tops, many of which have just dropped into the COS Black Friday sale.
COS has quietly become the fashion editor’s destination for elevated layering pieces: the famous Merino Wool Top, a piece that slots seamlessly under blazers, cardigans and dresses is a fail-safe wardrobe staple—so much so that COS now offers it in high-neck, crew-neck and slim-fit versions. And that’s just the beginning.
The brand’s cloud-soft Cable-Knit Jumper that looks twice as expensive as it is, and a whole roster of sleek wool cardigans and high-neck knits that make winter dressing feel considered rather than chaotic. Every piece shares the same COS DNA—clean lines, premium fabrics, and silhouettes that turn even the simplest outfit into something quietly refined.

What sets these pieces apart, though, isn’t just their polish. COS uses RWS-certified wool, meaning every fibre meets the Responsible Wool Standard, with strict guidelines around animal welfare and land management. If I’m investing in wool, I want to know it’s been sourced responsibly—and COS is one of the few high-street brands that can confidently make that claim.
Whether you’re commuting to the office layered under a tailored coat, heading out on a frosty weekend walk, or dressing up for an evening out, these wool staples are the kind of foundation pieces you'll lean on all winter long, and for many winters to come. Below, I’ve pulled together the chicest wool buys worth snapping up in the Black Friday sales before they inevitably disappear.
