The Bytomic Defender Head Guard is a dipped-foam, open-face sparring head guard built for semi-contact Taekwondo, Karate and Kickboxing. It's lightweight, hook-and-loop closed, and sized by head circumference. Find more dipped-foam protection across the Bytomic collection.
Fit tip: Use a flexible tape measure around the widest part of your head — typically just above the eyebrows and ears. Measurement A is head circumference; measurement B is the upper-head distance where the guard's crown sits. If you sit between two sizes, take the larger for the looser dipped-foam stretch.
| Size | A (Head Circumference) | B (Upper Head) |
|---|---|---|
| Small | 52cm | 50cm |
| Medium | 55cm | 53cm |
| Large | 59cm | 56cm |
| XL | 61cm | 58cm |
How to measure
- Head circumference (A): Wrap a flexible tape measure horizontally around the widest part of your head — just above the eyebrows and ears. Keep the tape snug but not compressed.
- Upper head (B): Note the snug distance from the crown of the head down to where the rear strap will close.
