Matt 'Mayhem' Biolos's signature template
delivers a lively combination of drive, hold and manoeuvrability. This versatile fin will feel reliable out on the open face or tight in the pocket.
Developed in conjunction with US shaper Matt Biolos.
Available in S, M and L sizes. (M + L = Tri or Tri-Quad options)
Same template scaled across three sizes.
Flat foil on the side fins, 80/20 foil on the quad rears.
Customised graphics tie back to the LOST brand.
Sitting in the Reactor Family, the FCS II 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. With noticeable geometric similarities to the Performer template, but with less sweep, it has a balanced outline with smooth curves and moderate area in the tip. The fin also has a relatively short base in contrast to the higher depth value of the fin. The same template features across all three sizes.
A wide range of conditions, particularly good in critical overhead waves.
Performance shortboards and hybrid models with the FCS II Fin System.
Please Note: this fin is designed to be used exclusively with the FCS II Fin System, and will not fit in the traditional FCS Dual Plug System.
