Sizing & Human-Centered Geometry

Our in-house industrial designers model earplugs around real anthropometric data -- tapered stems, angled fins, and anti-rotation grips keep the plug seated during butterfly, flip-turns and tumble dives.

    Small -- 10 to 13mm

    Children ages 4-10, narrow ear canals

Silicone Hardness & Wearing Feel

Specify Shore A hardness to match your target feel -- from pillow-soft kids' plugs to firm competition-grade seals.

30A

Ultra Soft

Cloud-like touch, deforms easily. Best for kids and all-day comfort.

50A

Balanced

Our most popular hardness -- soft seal with reliable retention during laps.

70A

Firm Pro

High retention -- recommended for competitive swimmers and divers.

Material toughness improved by 45% vs. standard LSR, maintaining elasticity after extended chlorinated-water use.

Watertight by Design

Multi-layer fin geometry creates sequential micro-seals along the ear canal. Combined with precision molding and controlled compression, our earplugs deliver reliable waterproofing lap after lap.

Sequential Fin Seals

Each fin forms an independent seal -- redundancy keeps water out.

IPX8 Water Resistance

Validated for continuous submersion in pool and open water.

Pressure Balance Option

Optional micro-vent channel reduces ear pressure during dives.
