OCTA Stand-Collar Heavyweight Sweatshirt

A half-zip stand-collar sweatshirt made with Teijin OCTA octagonal hollow fibers. Its unique structure creates a lightweight layer of air that retains heat for extended periods, while the soft interior is gentle on the skin. The slightly relaxed silhouette combines multiple panels with raglan sleeves for easy shoulder and arm movement. The stand collar reduces cold drafts around the neck. The concealed half-zip blends naturally into the body's seam, while the suede-like pull tab adds texture. Concealed hand pockets and modified stretch ribbing enhance storage, wind resistance, and heat retention.
