Men’s underwear styles for OEM and private label programs
Start from the silhouette. Each page below sets out the specification choices for one style — leg length, rise, front construction, fabric, waistband, branding and packaging — so your first brief is specific enough to quote and sample.
Boxer briefs
Fitted, contoured and leg-covering. Decide leg length, front construction and waistband before you request a quotation.
Specification guide →Trunks
The short-leg alternative to boxer briefs. Rise, leg-opening grip and edge finish matter most.
Specification guide →Briefs
The leg-free silhouette. Define rise, side width and leg-opening shape, then plan the multipack.
Specification guide →Boxer shorts
The loose silhouette in woven or knit. Choose fabric, fly and print method, and plan for shrinkage.
Specification guide →Seamless underwear
Knitted to shape with few side seams. Brief the knit structure, zones and size bands.
Specification guide →Performance underwear
Mesh panels, flatlock seams and grippers — with the test evidence your performance claims need.
