Custom Zip-Through Hoodies: What the Zip Does to Your Design
By The Velocity Wear Team
A zip-through hoodie has no full front panel, so your decoration plan has to change before your artwork does. The zip splits the chest into two narrow halves separated by a raised tape, which is why most zip-through runs put the main design on the back and keep the front to a small left-chest logo. Velocity Wear produces zip-through hoodies online from a 20-piece minimum using screen printing, DTF and embroidery, and the free Design Studio lets you see the split before you commit.
Where the Print Actually Goes on a Zip-Through
On a pullover you get one clean rectangle running from the neck rib down to the top of the pouch pocket. A zip-through gives you two panels instead, each roughly half that width, and the kangaroo pocket has usually been replaced by two side pockets that cut into the lower front as well. What is left is narrow and interrupted. The placements that work every time are the back, the left chest, and the upper sleeve.
The back is where the big graphic belongs. It is flatter and more forgiving than the front of a pullover, and the fabric sits under less tension there.
Why Printing Across the Zip Fails
Every decoration method has a physical reason it cannot cross a zip. Screen printing needs the mesh to make even contact with a flat platen; zip teeth lift the fabric by several millimetres, the squeegee skips the ridge and smears the edges. DTF needs an even press across the whole transfer, and the zip tape is a different material that neither takes the adhesive properly nor flexes with the rest of the print. Embroidery is worse again, because the hoop cannot clamp flat over hardware and a needle meeting metal teeth breaks.
The working rule is simple. Keep any decoration at least 30 to 40mm clear of the outer edge of the zip tape. Closer than that and the press platen or the hoop starts fighting the hardware even if the design itself never touches it.
Splitting a Design Either Side of the Zipper
You can split a design across both panels, and on the right artwork it looks deliberate rather than compromised. Two conditions apply. Each half has to read on its own, because the wearer will spend half the day with the zip partly open. And you have to accept the halves will never align perfectly when worn, since the zip carries ease and the body pulls the panels apart unevenly.
Good candidates have a natural vertical break already: a two-word name, a symmetrical emblem with a gap at the centre, a repeated motif. Bad candidates are fine serif type, thin outlines, and anything where a two-millimetre misregistration is visible. If your logo only works whole, put it on the back and put a small mark on the chest.
Zip Hardware Tells People What the Garment Cost
Three zip types cover most of the market. Metal reads as premium and adds weight, though it can mark lighter fabrics and it is the least comfortable against the chin. Moulded plastic is tough, light and common on outdoor-leaning styles. Coil is the flattest and cheapest, and on a mid-weight hoodie nobody notices it, which is often exactly what you want.
Two details matter more than the material. A chin guard, the small fabric tab at the top of the zip, is the difference between a hoodie people zip fully and one they leave half open. And a double-ended zip, which opens from the hem as well as the neck, is genuinely useful for anyone who sits down in the garment all day.
Weight and How the Front Edges Behave
Zip-throughs expose fabric weight more than pullovers do, because the front hangs open and unsupported. At around 280 GSM the front edges roll and flap and the garment reads as a giveaway. At 330 to 350 GSM the panels hang straight and the zip sits in a clean line. If your budget only stretches to a light fabric, a pullover will hide it better than a zip-through will.
Zip-Through or Pullover for a Team Order
Zip-throughs win when people move between temperatures: retail staff on and off a shop floor, event crews, anyone layering over a polo. Pullovers win when the point of the garment is a large chest graphic. If your brand identity is a wordmark that has to sit on the chest, the pullover is not a compromise, it is the correct product.
- Ask for placement measured from the shoulder seam and from the zip tape, not just described as "left chest".
- Check the pocket position on the specific style, because side pockets sit higher on some blocks and eat into the print area.
- Order the same design on a pullover and a zip-through only if it works split, otherwise vary the artwork.
- Confirm the zip type and whether it is double-ended before approving, since it changes the look more than most people expect.
- Allow around 10 to 15 working days from artwork approval for screen printing or embroidery, not from the day you order.

Proofing a Zip-Through Before the Run
Lay the design out in the Design Studio and look at it closed, then imagine it open. The instant price calculator shows how cost moves as quantity rises, with bulk discounts reaching up to around 40%. Minimum order is 20 pieces with sizes mixed freely, and UK delivery is typically 2 to 5 working days after dispatch.
