The Control Series is an upgrade to our fiberglass line. Now featuring a layer of uni-carbon strips which give them a much more dynamic response. This addition also allowed us to give these fins a thinner profile. This translates to a lighter-weight fin and a decrease in drag without sacrificing the durability or control you’d expect from a fiberglass fin. The Control Series is also a great addition to our Ride Number story, contrasting with Speed Generating fins such as Blackstix or the Generation Series. These fins will fit into the 1 to 3 Ride Number range as the most Speed Controlling options in our line. Make sure to have a set of these in your fin quiver for powerful conditions.
