What Causes Neckline Stretching in Men's Performance T-Shirts?

Neckline stretching can result from unstable binding, unsuitable tension, or poor recovery.

The factory needs clear instructions for component dimensions, placement, seam construction, and permitted variation. Check the detail against an approved reference and movement trials, especially at high-stress joins; small assembly differences can affect symmetry, comfort, or durability even when the overall garment looks acceptable. Check after repeated dressing and care.
