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

This 70 cm / 27.56 in N5 / #5 TPU-coated water-resistant combi zipper is designed for parkas, long coats, softshell jackets, hooded outerwear, and technical apparel that need a stable front closure plus adjustable comfort at the lower hem. The main slider closes the garment normally. The secondary lower slider opens upward from the hem when the wearer needs additional space for walking, sitting, driving, cycling, climbing stairs, or layering.

For long outerwear, this small adjustment can make a noticeable difference in daily comfort. The lower hem can be opened only as much as needed, reducing tension at the front of the coat while keeping the garment connected. This is the practical advantage of a combi zipper in long parkas and technical outerwear designs.

What Is a Combi Zipper?

A combi zipper is used in outerwear where the garment needs normal front closure plus controlled opening at the lower hem. The zipper does not detach into two separate halves. Instead, the lower slider moves upward to create an adjustable opening in the hem area.

Choose a separating zipper when the full jacket front must disconnect at the bottom. Choose a combi zipper when both front panels should remain connected while the lower edge needs more flexibility. This distinction matters when selecting a zipper for parkas, long coats, softshell jackets, and hooded technical outerwear.

What Does TPU Coating Add?

The TPU-coated surface helps reduce direct water exposure around the zipper line. It is useful for parkas, softshell jackets, outdoor coats, rain-oriented outerwear, and technical garments that may be exposed to moisture or damp conditions.

TPU coating also creates a smoother, more technical appearance. Combined with the N5 / #5 zipper structure, it gives the front closure a more streamlined and performance-focused look. Black 322 tape works especially well with black, charcoal, navy, dark gray, deep green, and technical outdoor collections.

Water-Resistant Zipper vs. Fully Waterproof Garment

A TPU-coated water-resistant zipper can improve protection along the front zipper line, but it does not make a finished coat fully waterproof by itself. Final weather protection depends on shell fabric, seam tape, seam construction, storm flaps, pocket construction, hood design, lining, and complete garment assembly.

Before regular production, make a sewn sample with the actual shell fabric, lining, placket construction, and seam allowance. Check zipper travel, lower-slider function, coating behavior, hem alignment, seam bulk, and garment performance under its intended conditions.

Where Can a 70 cm / 27.56 in Combi Zipper Be Used?

This zipper is suitable for parkas, long coats, softshell jackets, outdoor apparel, technical workwear, long hooded garments, and products that need adjustable opening at the lower hem. The 70 cm / 27.56 in length can fit many adult outerwear patterns, but the finished front opening should always be measured before ordering.

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

N5 / #5 Construction for Parkas and Outerwear

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

For lightweight dresses, skirts, blouses, or fine shirts, a smaller concealed or closed-end zipper is generally more suitable. For heavily padded winter parkas or products designed around oversized visible teeth, compare larger molded zipper constructions before production.

Black 322 Tape in Technical Outerwear

Black 322 tape coordinates naturally with black, navy, charcoal, dark gray, deep green, and performance-inspired outerwear. On stone, beige, white, light gray, or color-blocked shells, it can become a deliberate contrast line that adds a sportier technical appearance.

For a more refined garment finish, match the zipper tape with lining, drawcords, rib trim, pocket zippers, snaps, buttons, eyelets, logo plates, and other visible hardware. Consistent material choices help the finished product look more coordinated and professionally developed.

Sewing Guidance for TPU-Coated Combi Zippers

• Align both zipper tapes at the neckline and hem before stitching.
• Confirm that the lower slider can move upward from the hem smoothly.
• Keep bulky lining, thick seams, and rib trim clear of the lower slider path.
• Avoid sharp creases and direct high heat on the TPU-coated zipper surface.
• Check front-edge flatness, hem alignment, and lower-opening movement on a sewn sample.
• Use the real shell fabric, lining, placket, and seam construction before full production.

Custom Technical Zipper Requests

TPU-coated water-resistant combi zippers can be developed with custom lengths, tape colors, slider styles, branded zipper pulls, and collection-specific technical requirements. Share the garment type, target zipper length, color direction, expected quantity, and any physical sample or technical reference for a custom-production review.

Frequently Asked Questions

Is this a separating zipper?

No. This is a combi zipper. The two sides remain connected at the bottom.

What does the lower slider do?

The lower slider moves upward from the hem to create a controlled opening for more movement room.

What garments can use this zipper?

It is suitable for parkas, long coats, softshell jackets, hooded outerwear, outdoor apparel, and technical garments.

Does TPU coating make the full jacket waterproof?

No. It supports water resistance at the zipper line. Full waterproof performance depends on fabric, seam tape, storm flaps, pockets, and garment construction.
