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

Fit note: Match your measured waist to the table — measure where the band will sit. The ice-silk knit has plenty of stretch, so the ranges are reliable. Sizes run S to XXL, fitting up to a 101cm (40") waist; if you are between two sizes, take the larger one.

Fits waist is the body measurement each size is designed for. Blank cells mean no size in this range fits that build — the largest size sold is XXL. Waist measurement always wins over the quick guide. Measurements are taken by hand and may vary slightly between pairs.

A heart where you least expect one

Under clothes this is the most invisible trunk in the drawer — ice-silk nylon with no side seams, flat bonded leg edges and a label printed inside, so there is nothing to show through anything. Then you take the trousers off and there is a heart cut into the back, filled with sheer mesh. Not an opening: a panel. Covered, transparent, and shaped exactly the way it sounds.

The front is a large moulded pouch with a lined gusset, and the ice-silk knit is thin, cool to the touch and quick to dry. Two colours — white, where the mesh reads soft and obvious, and black, where you only catch the heart when the light is right.

  • Heart-shaped mesh panel — sheer but covered, set into the seat
  • No side seams — bonded panels and flat leg edges leave no visible line
  • Ice-silk nylon body — thin, cool-touch, opaque and quick-drying
  • Large moulded pouch — shaped front with a nylon-lined gusset
  • Printed tagless label — nothing sewn in to scratch
  • Boxer trunk cut — short leg, full coverage everywhere but the panel
  • Two colours — black and white
Fabric & Care

Ice-silk nylon with a nylon mesh panel and a nylon-lined gusset. Smooth, cool against skin, highly elastic and quick to dry.

Hand wash or machine wash cold. Do not bleach. Tumble dry on low or hang to dry — hanging is kinder to the bonded edges. Do not iron. Keep the mesh panel away from velcro and hooks.

FAQ

Who is this for?
Gay men, femboys, crossdressers and twinks who want a trunk that behaves under clothes and does not behave at all without them.

Is the back open?
No. The heart is a sheer mesh panel sewn into the seat — you can see through it, but the seat is covered. Nothing is exposed.

Is the rest of it see-through?
No. Only the heart panel is sheer. The ice-silk body is opaque in both black and white.

Will it show under trousers?
No lines from the pair itself — no side seams and no hemmed leg openings, which is where visible lines come from. The mesh panel is flat and does not print through.

Which size should I take?
Match your measured waist to the size guide on this page. The knit stretches well, so the ranges are reliable; if you are between two sizes, take the larger one.

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