What to Compare Before Buying
- Hat fit: This insert is made for a baseball hat. Check that the hat shape and internal space match the 17 x 21 x 12 cm size.
- Protection level: It provides basic protection against minor bumps, scrapes and low-contact use. Compare that with the level of protection you need.

Confirm that you want an insert rather than a full safety helmet, and check the baseball hat fit against the 17 x 21 x 12 cm size before choosing an offer. If you need more than basic protection, look for a different head protection type.
