Performance Muscle Tank — Custom OEM

The Performance Muscle Tank is a customisable sleeveless training top manufactured by Giborn Apparel for gym, fitness and performance labels. The armhole is dropped and the shoulder narrowed so the garment clears the deltoid during overhead movement, and the neck is bound rather than ribbed to keep bulk off the collarbone. Fabric is a quick-dry knit chosen for how fast it releases moisture rather than how it feels on a hanger. Part of our men’s singlets range, it is the block most gym brands build their core range around.

Customization Options

• Armhole depth and shoulder width adjusted for coverage or exposure
• Moisture-wicking polyester, poly-elastane and cotton-blend performance knits
• Bound, ribbed or coverstitched neckline
• Body length graded for a cropped, regular or long fit
• Reflective heat transfer, silicone and small-format embroidery
• Side seam or seamless tubular construction

Why Produce With Giborn

Performance knits stretch under the needle, so seam tension has to be set for the specific fabric or the side seam ripples after the first wash. Those settings are recorded against the style under our ISO 9001:2015 system and re-verified during the in-line inspection gate. The full sequence is on our manufacturing page.

MOQ, Sampling & Lead Time

Flexible MOQ · Sampling 5–15 days · Bulk 30–60 days. Performance styles are wash-tested for stretch recovery before sign-off, which adds a few days and prevents a bulk run that loses its shape. That test is standard in our OEM development route.

Send your fabric target and fit reference and we will sample both. Before agreeing an inspection level, our explainer on AQL inspection is a useful primer.
