Matrix Fins - Unbelievable Performance!    (read these testimonials by satisfied customers...)

20 Fathoms Home

Bulletproof Construction

These advanced Glass Fiber Composite fins are manufactured using premium materials and craftsmanship, resulting in a structure which is nearly as light as carbon fiber but has a much higher ability to absorb energy. 

The result - Similar performance to Carbon Fiber (light weight, high modulus of elasticity) but highly resistant to impact.  Exclusively used by many current spearfishing champions, these fins were used by the top competitors at every U.S. National Championships since 2002.

Customizable Stiffness

The Matrix fins are available in five standard stiffnesses, or you can order a specific stiffness.












Extra Stiff  

Do not be tempted into selecting stiffer blades because of your experience with other products.  Our most popular blades are the No. 3 stiffness.  These fins are very efficient.  Softer blades are very effective and conserve energy.

"You won't believe the thrust of these fins!!!"

"They perform like carbon fiber, but they're virtually unbreakable..."
