Long Sleeve Undershirts Manufacturer
Custom long sleeve undershirts for layering and seasonal basics. Sleeve shape, cuffs, body length, fabric weight and neckline construction are developed to your approved sample and measurements.
Develop the sleeve, cuff and body as one fit
Long sleeve undershirts require more than adding length to a short-sleeve body. Shoulder position, armhole shape, sleeve taper and cuff opening all contribute to how the garment fits under another layer.
We review those details with your chosen fabric and neckline. Cotton jersey, stretch blends and rib knits can be considered according to the intended feel and fit. Any thermal or other performance requirement should be defined and reviewed for the specific project.

Can I choose ribbed or plain cuffs?
Yes. Share your preferred cuff construction, opening and measurements. We review the finish with the selected fabric and sample.
Can you develop tall or extended sizes?
Custom grading can be discussed from your measurement sheet. The size range, sleeve length and body proportions are confirmed before production.
Do you provide a fixed thermal performance rating?
Performance depends on the selected fabric and construction. If you require a specific test or performance target, share the requirement so testing scope, availability and costs can be reviewed.
Planning your long sleeve undershirt programme
Start with sleeve measurements
Confirm sleeve length, upper-arm fit and cuff opening rather than treating sleeve length as the only variable.
Choose weight for the layering programme
Material and GSM should be selected for coverage, stretch and intended climate. Rib structures and jersey fabrics create different silhouettes.
Review the complete size set
Check how sleeve and body proportions change across sizes, then confirm grading and final measurements before production.
