Charlie Zip Sweater

This black rib-knit sweater relies on a tight, vertical tension to hug the torso, balanced by a sharp mock neck and a gold-tone loop zipper that leans into a 70s-inflected sport aesthetic. The heavy-duty hardware acts as the focal point against the matte, uniform texture of the knit, which provides enough structure to tuck neatly into high-waisted bottoms without bunching. It’s a utilitarian base layer that trades slouch for a clean, streamlined silhouette.

Safety Rating: Lowest

Analysis: The blend of 55% viscose and 45% nylon creates a synthetic-heavy fabric that lacks natural breathability and is prone to heat entrapment. Viscose processing often involves high chemical toxicity, while the reliance on nylon—a petroleum-based plastic—poses concerns regarding microplastic shedding and limited skin-surface ventilation.
