 Running Cap Size Guide

Our cap sizing reflects the actual dimensions of the product in a relaxed state. Measurements may vary slightly by ±1cm due to fabric stretch and production tolerances.

Since our running caps are designed for performance and comfort, we recommend selecting your size based on head circumference. The fit should be snug but not tight, ensuring stability during your runs.

If you're between sizes, we suggest choosing the larger size for a more relaxed fit.
