Matt 'Mayhem' Biolos's 'MB' shaper fin. Reliable on the open face, or in the pocket.

Size small

Performance Core Carbon

The MB template offers freedom to perform tight turns in the pocket with an emphasis on speed.
Sitting in the reactor family, the MB is considered a high performance fin because it responds incredibly fast, but still offers enough control so you can confidently lay into a turn with plenty of force.
