After a lengthy period of experimenting with materials FCS settled on 'Glassflex' for the M series of fins. This allows precision foiling at an incredible price.
The M Series fins are a replacement for the old G series - they are designed as an 'entry level' price fin and will be fitted as standard by most shapers on new FCS boards.
What even FCS can't have fully expected is the reaction to this fin from surfers - even pro riders with unlimited budgets are riding this fin for the performance it offers. The inside foil reduces stall and increases speed and the fins just look a world away from the old G Series (to the point where we'd really suggest considering an upgrade if you're on the Gs).
Looks great too - you've got a surreal slightly translucent green glow off the fin in to replace the old flat white or black options.
Size
Available in three sizes (M-3/M-5/M-7) with the M-3 better for lightweight/younger riders (or anyone liking a super loose ride) the M-5s for most of us and the M-7 for bigger waves and power surfing.
Much more info coming soon... In the meantime please give us a shout with any questions.
