Configuration: 5-Fin Set (Thruster + Quad Options)
Construction: Endorfins Composite / Carbon Inlay
Template: Kelly Slater KS1 Pivot Template
The ENDORFINS KS1-M is based on Kelly Slater’s original fin template, known for quick pivot, fast response, and a lively feeling in the pocket. The Outerknown edition keeps that performance character while offering a clean premium finish and strong all-around versatility.
As a 5-fin set, this package gives you the option to run your board as a thruster or quad depending on the session. That makes it especially useful in a retreat quiver where adaptability matters and guests may want to tune the same board for different moods and conditions.
This set is a strong fit for surfers who like a more performance-oriented feel and want a fin that responds quickly when they push through tighter turns or more critical sections.
This fin set is part of the Natural Mystic Private Quiver Collection and is available exclusively to retreat guests during their week at the retreat. Your setup will be dialed and ready when you arrive.
All equipment in the Natural Mystic Private Quiver Collection is selected and maintained for performance, feel, and overall experience.
Damage Policy:
Guest is responsible for any damage beyond normal wear. Lost or damaged fins will be charged at replacement cost. Always check your equipment before entering the water and avoid contact with reef or rocks.
