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

Fit note: Waist is the figure to go by; height and weight are a cross-check. With nearly a third spandex the knit stretches a long way, so sizes cover a wide range — if your waist falls between two rows, take the larger size. Sizes run M to XXXL, fitting up to a 107cm (42") waist.

Long legs, and nothing hidden

A long-leg boxer that runs to mid-thigh, cut from ice silk thin enough to read as tinted glass. The length is the practical part — the leg covers the whole area where thighs rub, with flat non-rolling hems that stay down instead of riding up. The transparency is the other part, and it is not subtle: front, back and legs are all a single unlined layer.

Nearly a third of the fabric is spandex, so it moves with you and snaps back rather than bagging at the knee. The body is knitted seamlessly with reinforced sides, and a seamed U-pouch holds the front with a lined gusset behind it. Five colours — from a barely-there white to a deep grape purple.

  • Long leg — hem sits mid-thigh, covers the chafing zone
  • Ultra-thin see-through ice silk — unlined throughout
  • 69% nylon, 31% spandex — very high stretch with strong recovery
  • Seamed U-pouch — shaped front with a nylon-lined gusset
  • Seamless body — no side seams, reinforced at both sides
  • Non-rolling hems — flat leg openings that stay put
  • Quick-drying — the nylon knit sheds moisture fast
  • Five colours — black, white, grey blue, orange and purple
Fabric & Care

69% nylon, 31% spandex ice-silk knit with a nylon-lined gusset. Cool to the touch, extremely elastic and quick to dry.

Hand wash cold, or machine wash cold in a mesh laundry bag on a delicate cycle. Do not bleach. Do not tumble dry — heat destroys fine nylon and kills the stretch. Hang to dry away from direct sun. Do not iron. Keep away from velcro and anything with a hook.

FAQ

Who is this for?
Gay men, femboys, crossdressers and twinks who want the long-leg boxer shape with none of the coverage. It is also the practical choice if short briefs leave your thighs rubbing.

How see-through is it, really?
Completely. One unlined layer everywhere except the gusset — and that includes the seat and the legs. It shows through light trousers too. Please buy it knowing that.

How long is the leg?
Mid-thigh — noticeably longer than a standard trunk, roughly where cycling shorts sit. The hems are flat and do not roll up.

Which size should I take?
Go by the waist range in the size guide on this page, and use the height and weight columns as a cross-check. With nearly a third spandex the fabric stretches a long way, but stretched to its limit is not the same as comfortable — 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.
