📏 Size Chart & Fit Guide ⚠️ Runs small — check before ordering

Fit note — this pair runs small. The recommended waist ranges below sit narrower than a standard brief, so measure your waist and match it to the table rather than ordering the size you usually wear. The waistband has a large stretch reserve and will physically go much wider than the recommended range, but that is maximum stretch, not comfortable wear — order by the recommended range, and if you are between two sizes take the larger one.

A sports brief with two things missing

Everything about this pair reads like a classic athletic brief — wide striped waistband, clean white knit, full seat, no fuss. Then you notice the openings. A keyhole cut-out sits at the centre front just under the band, and a second one sits in exactly the same place at the back. Nothing else about the shape is unusual, which is what makes it work: from the waist down it covers you completely, and the two cut-outs do all the talking.

The fabric is modal rather than cotton — softer, smoother, with more drape and a matte finish that does not go shiny under light. It is fully opaque, so this is a cut-out piece rather than a sheer one.

  • Keyhole cut-out front and back — matched openings under the waistband, front and rear
  • 95% modal, 5% spandex — softer and smoother against skin than cotton, with a light stretch
  • Fully opaque — nothing shows through the fabric itself
  • Low rise — sits below the navel
  • Full seat — brief coverage at the back apart from the cut-out
  • Wide striped waistband — holds firm without rolling
  • Three colours — white, blue and black, all with the same contrast band
Fabric & Care

95% modal, 5% spandex. Modal is a soft, breathable fibre with a smooth matte surface and good moisture handling; it holds colour well and resists the greying that cotton picks up over time.

Machine wash cold on a gentle cycle with similar colours. Do not bleach — it will yellow the white and strip the band. Hang to dry; tumble drying shortens the life of the elastic. Warm iron only if needed, never on the waistband.

FAQ

Who is this for?
Gay men, femboys, crossdressers and twinks who like the look of a plain sports brief but want one detail that changes the whole read of it.

How big are the openings?
Both are small horizontal keyholes sitting directly under the waistband, front and back. They are openings in an otherwise complete brief — this is not an open-front or open-back cut.

Is the fabric see-through?
No. The modal knit is opaque in all three colours, including white.

Which size should I take?
This pair runs small. Measure your waist and match it to the table in the size guide on this page rather than ordering the size you usually wear. With only 5% spandex there is less stretch reserve here than in a nylon pair, so getting the waist right matters more.

How is it shipped?
In plain, unmarked packaging. Nothing on the outside names the contents or the store.
