180 GSM Sleeveless T-Shirts

Sleeveless Round-necks (regular) is a slim-fit, round-neck block engineered for low GSM cotton and cotton-lycra knits with activewear-oriented ease. The neckline is finished with a self-collar treatment: a 0.5 inch self-fabric band rather than a separate rib, chosen to keep bulk low while maintaining edge stability and comfort. The armhole curve is drafted to reduce gaping and maintain shoulder coverage while allowing overhead mobility; balance between front and back scoop is controlled to avoid drag lines across the chest. Grading follows a slimmer profile through chest and waist across XXS to 3XL, maintaining proportional shoulder width and armhole depth to preserve the intended close fit across sizes.

Construction prioritizes a smooth, non-bumpy interior and exterior at contact areas. Flatlock with autocut is applied where specified to trim excess and produce flat seams along side seams and around the neckline attachment, improving wear comfort and appearance. CAD-based pattern development with manual cutting ensures repeatable armhole symmetry and neck opening control; rib cutting and roll machines are leveraged to maintain consistent 0.5 inch self-band width and circumference. This pattern is optimized for lightweight knits; pattern tolerances and feed are set to prevent edge wavy distortion at the neck band during assembly. Adjustments for program-specific lengths or ease can be executed while preserving the base slim grading logic.
