Cleto Reyes Groin Guard Size Guide
Cleto Reyes Foul Proof groin guards are sized by waist measurement. Measure around your waist at the line where the guard's belt will sit (roughly at the navel, not at the hips), keeping the tape level and snug. If you are between sizes, go up: a too-tight guard restricts movement and rides up during footwork. Cleto Reyes runs slightly smaller than other major brands, so most fighters take one size up from their jeans size.
| Size | Waist |
|---|---|
| Small | 26" – 31" (66 – 79 cm) |
| Medium | 32" – 35" (81 – 89 cm) |
| Large | 36" – 39" (91 – 99 cm) |
| XL | 40" – 44" (102 – 112 cm) |
How to measure
- Waist — measure around your natural waistline at navel height, where the guard's belt will sit. Tape level, snug not tight, no clothing layers underneath.
- Cleto Reyes fit note — this brand runs slightly smaller than other major boxing brands. If your waist measurement lands on a size boundary, take the larger size.
- Coverage check — the front shell should cover from just below the navel to the top of the thigh, with the cup centred. If the bottom edge digs into your thighs when you sit, size up.
