Size Chart

Measure where the garment sits — low on the hips, below your natural waist. That's the number that matters.

G-string / thong

Garment measured flat, unstretched. Fabric stretches up to an extra 20cm, so don't size off the flat measurement alone.

Size Waist (cm) Approximate trouser size Approx weight
XS 75 30 55–65 kg
S 80 32 65–75 kg
M 85 34 75–85 kg
L 90 36 85–95 kg
XL 95 38 95–105 kg
2XL 100 40 105–115 kg
3XL 105 42 115–125 kg
4XL 110 44 125–135 kg
5XL 115 46 135–145 kg
6XL 120 48 145–155 kg

Between sizes? Size down for a tighter, firmer fit — size up for a relaxed fit.
Big Boy Pouch adds ~5cm extra pouch space — same size chart applies.

Rip String (thong swimwear)

Full flat measurement, ±1cm tolerance for stretch. Cut higher than the Reef Briefs, so the two won't feel the same at the same size label.

Razor Briefs (underwear)

Runs smaller and tighter than the Thong for a firmer, more secure fit — if you're between sizes here, sizing up is usually the safer call.
