A half-zip blanket hoodie needs enough opening clearance for hair, earrings and any collar worn underneath. Practise the zip slowly while looking in a mirror before using it by feel. The test should reveal snags and crowding without pulling hair through the slider path.

Clear the zip corridor

Tie back long hair or move it fully behind the shoulders. Remove dangling earrings and necklaces for the first rehearsal. Flatten the underlayer collar, then identify the line the zipper follows from the chest toward the neck.

With the garment on, hold the fabric beside the zipper with one hand and move the slider slowly with the other. Stop immediately if hair, a drawcord or collar edge enters the path. Never jerk the slider past resistance.

Repeat with the real collar layers

1. Try the hoodie over a collarless top and note the opening needed to put it on comfortably.
2. Repeat with the collared layer you are likely to wear.
3. Turn the head gently left and right with the zip at the preferred height.
4. Lower the zip before removing the hoodie; do not pull a narrow opening over the head.

If the collar bunches, try folding it consistently inside or outside rather than letting one side drift toward the teeth. If hair repeatedly enters the corridor, keep it secured until the zipper is in position.

Choose a repeatable stopping point

Use a visible garment feature as the preferred zip height—for example, aligned with the top of the underlayer collar—rather than counting teeth. Confirm that the position leaves comfortable neck and chin clearance while seated as well as standing.

This is an operation check, not evidence that a zipper cannot snag. Children or anyone needing assistance should have help appropriate to the garment’s instructions.
