Octa Heavyweight Stand-Collar Sweatshirt

This stand-collar half-zip sweatshirt uses Teijin OCTA octagonal hollow fibers to create a lightweight air layer for lasting warmth, with a soft, skin-friendly interior. The relaxed fit combines multi-panel construction with raglan sleeves for unrestricted shoulder and arm movement, while the stand collar helps block cold air. The concealed half-zip integrates cleanly into the seam lines and is finished with a suede-style puller. Hidden hand pockets and shaped stretch ribbing improve storage, wind protection and heat retention.
