      If you're anything like me—the type that refuses to feel cold, even during the height of winter—you understand the significance of layering. As I type this, the temperature outside is at zero, intensifying my commitment to dressing warmly. My not-so-secret trick for staying cozy while maintaining a polished look? Investing in winter essentials like COS's outstanding collection of merino wool tops, many of which are featured in the COS Black Friday sale. COS has subtly positioned itself as the go-to for fashion editors seeking refined layering pieces: the well-known Merino Wool Top, which fits effortlessly beneath blazers, cardigans, and dresses, is an indispensable wardrobe classic—so much that COS now provides high-neck, crew-neck, and slim-fit versions. And that’s merely the start. The brand's ultra-soft Cable-Knit Jumper appears much more luxurious than its price indicates, along with a variety of sleek wool cardigans and high-neck knits that ensure winter attire feels thoughtful instead of chaotic. Each item embodies the COS ethos—clean lines, quality fabrics, and shapes that elevate even the simplest outfits into something subtly sophisticated.

      Junior fashion editor Imani showcases just one of the many items in COS's Black Friday sale, such as the Flecked Chunky Wool-Alpaca Cardigan (originally £119, now £95.20) (Image credit: @imani_athina). What distinguishes these pieces, however, is not just their elegance. COS utilizes RWS-certified wool, ensuring that every fiber complies with the Responsible Wool Standard, which imposes strict rules surrounding animal welfare and land management. When investing in wool, I prefer to know that it has been ethically sourced—and COS is among the few upscale high-street brands that can confidently assert this claim. Whether you're commuting to work under a tailored coat, venturing out for a chilly weekend stroll, or dressing up for an evening occasion, these wool essentials serve as the foundational pieces you'll rely on all winter and for many to come. Below, I've compiled a list of the finest wool items worth grabbing in the Black Friday sales before they're inevitably gone.
