The foam padding in the Samshield helmet is mandatory. Each set of foam is designed for a specific helmet shell size (S, M, or L). The foam size determines the final size of your helmet:

• Foam size S fits sizes 52 to 56
• Foam size M fits sizes 55 to 58
• Foam size L fits sizes 57 to 61

The Samshield foam is very comfortable as it has a "memory foam" quality. It perfectly adapts to the shape of your head and prevents the helmet from shifting during vigorous movements. Machine washable at 30°C on a gentle cycle.
