70 cm / 27.56 in N5 / #5 TPU-Coated Water-Resistant Combi Parka Zipper ENC0070SG

This 70 cm / 27.56 in N5 / #5 TPU-coated water-resistant combi parka zipper is designed for long outerwear that needs practical front closure and adjustable lower-hem comfort. The main slider provides normal zipper closure. The secondary lower slider can move upward from the hem, allowing the wearer to create a controlled opening when extra movement is needed.

This makes the zipper especially useful in parkas, long coats, softshell jackets, hooded outdoor garments, and technical apparel. When walking, sitting, driving, cycling, or layering clothing, the lower hem can be adjusted without opening the entire garment front.

Combi Zipper Function for Parkas and Long Coats

A combi zipper is used when the garment should remain connected at the bottom but still needs adjustable room at the hem. The lower slider moves upward to create a controlled opening. This is useful for long outerwear where comfort and mobility matter as much as front closure.

This product is not intended to separate into two independent zipper halves. For garments that must detach completely at the hem, choose a separating zipper instead. For parkas and long coats that need lower-hem adjustment, a combi zipper is the more suitable solution.

TPU-Coated Water-Resistant Surface

The TPU-coated zipper surface helps reduce direct water exposure around the zipper line. It can be useful for parkas, softshell jackets, outdoor coats, rain-oriented garments, and technical apparel exposed to moisture or changing weather conditions.

TPU coating also gives the zipper a smoother and more technical appearance. Black 322 tape can blend naturally with black, charcoal, navy, deep green, dark gray, and performance-inspired outerwear. On lighter shell fabrics, it can create a deliberate contrast detail.

Water Resistance Depends on Full Garment Construction

TPU coating can support water resistance at the front zipper line, but it does not make a finished jacket completely waterproof by itself. Shell fabric, seam tape, seam construction, storm flaps, pocket structure, hood design, lining, and overall assembly all affect the final level of weather protection.

Create a sewn sample using the actual shell fabric, lining, front placket, and seam allowance before production. Check lower-slider movement, zipper travel, coating behavior, hem alignment, seam bulk, and the garment’s suitability for its intended conditions.

70 cm / 27.56 in Length Selection

The 70 cm / 27.56 in length can work well for many adult parkas, long coats, softshell jackets, and hooded outerwear designs. Measure the finished front opening rather than selecting zipper length from garment length alone.

Check collar or hood construction, placket width, lining, hem, rib trim, seam allowance, pocket placement, and the wearer’s movement needs. Selecting the correct zipper length helps prevent uneven hems, restricted lower movement, and front-edge distortion.

N5 / #5 Construction for Outerwear

N5 / #5 is suitable for garments that need a more substantial zipper line than fine dresswear. It is easy to grip and proportionate for many parkas, softshell jackets, technical coats, and outdoor products.

For lightweight dresses, skirts, blouses, or fine shirts, a smaller concealed or closed-end zipper is normally more appropriate. For very heavy parkas or products designed around oversized visible teeth, compare larger molded zipper constructions before production.

Sewing Guidance for TPU-Coated Combi Zippers

• Align both zipper tapes at the neckline and hem before stitching.
• Check that the lower slider can move upward from the hem without resistance.
• Keep bulky lining, thick seams, and rib trim clear of the lower slider area.
• Avoid sharp folds and direct high heat on the TPU-coated zipper surface.
• Test hem alignment, zipper movement, and lower-hem opening function on a sewn sample.
• Use the actual garment fabric, lining, placket construction, and seam allowance before full production.
