ArenaSpec System
Three Components. One Perfect Surface.
Every ArenaSpec is built from three engineered components —
mixed to a ratio that matches your discipline, your arena, and your goals.
We analyze your sand, assess your discipline, and prescribe
the exact FIBR · FLEX · LOCK ratio your arena needs.
Part of the ArenaSpec™ system
FLEX is one module of FIBR · FLEX · LOCK — and ships on its own.
FLEX is prescribed as the cushion & shock absorption component inside a custom ArenaSpec™ blend. You can also order FLEX independently as a standalone additive for your existing sand — no full system required.

Landings finally feel soft without the surface being deep or unstable. My horse comes out balanced and willing — and I love that it's 100% bio-based.

We added FLEX to our hunter ring before show season and got compliments all summer. The footing is forgiving but still has push — exactly what we wanted.

Easy to blend in with a normal drag pass, and the cushion has held up across two New England winters. Totally worth it.
