These chunky moulded plastic zips are built for outerwear applications where a standard zip would not cope. The Delrin resin teeth run smoothly, resist snagging, and hold up well to repeated use, chemical cleaning, and exposure to the elements. The two-way open-end mechanism allows the zip to be opened from either the top or the bottom — a practical feature for long coats, riding jackets, sleeping bags, and any garment where ventilation or ease of movement matters. A useful stock for dressmakers, outerwear makers, and anyone working on coat and jacket repairs.
