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

Fit note — this pair runs small. The supplier recommends taking one size up from the size you usually wear. Match your measured waist to the table below rather than going by the letter, and if you are between two sizes, always take the larger one.

M 67 – 69 26.5 – 27 34

Fits waist is the body measurement each size is designed for. Flat waist (half) is the band measured laid flat and unstretched, edge to edge — double it for the full relaxed circumference. Measurements are taken by hand and may vary slightly between pairs.

Mesh in front, nothing at the back

From the front these are simply sheer mesh boxer trunks — light, breathable nylon net with a shaped pouch and a short straight leg. Turn around and the design shows its hand: two large round openings, one over each cheek, cut cleanly through the back panel and bound at the edges. Nothing across the seat but the frame around it.

The mesh itself is fine enough to see straight through, so the whole garment reads as outline rather than cover. Five colours — the neon yellow and red make the most of the shape, black and navy play it slightly straighter, white hides nothing at all.

  • Round cut-outs at both cheeks — the back is fully open across the seat
  • Sheer nylon mesh — see-through, unlined, very light
  • Boxer trunk shape — short straight leg, not a brief
  • Shaped front pouch — with a nylon-lined gusset
  • Breathable — open net keeps air moving in hot weather
  • Five colours — white, black, navy, red and neon yellow
Fabric & Care

Sheer nylon mesh throughout with a nylon-lined gusset. Light, stretchy and very 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 is what kills fine nylon. Hang to dry away from direct sun. Do not iron. Mesh snags easily; keep it away from velcro, hooks and rough nails.

FAQ

Who is this for?
Gay men, femboys, crossdressers and twinks who want the boxer shape with the back taken out of it. This is a bedroom and photo piece, not something to wear under jeans.

How open is the back, exactly?
Fully. Two large round openings sit over the cheeks with only a narrow bound frame around them — the seat itself is bare. Check the rear photos before ordering.

Is the mesh see-through?
Yes, completely. It is a single unlined layer of fine net; only the gusset is lined. Please buy it knowing that.

Which size should I take?
This pair runs small — the supplier recommends going one size up from your usual. Match your measured waist to the size guide on this page and take the larger size if you are between two.

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