How to Correctly Measure Your Head

Using a soft measuring tape, measure around the crown of your head at the largest diameter. Start approximately 2cm above your eyebrows, ensuring the tape is positioned above the ears and around the back of your head at the largest point. The size guide below will help determine which helmet size you need.

The chart measurements pertain to the glove itself, not the hand. We suggest allowing approximately 2-3cm between the actual hand measurement and the glove size, taking into account the internal lining of the glove.

For instance, for men: If a customer's hand measures 10cm across the palm, they would need Spada size M (mens) gloves, as size M corresponds to 12cm.
