Protect your smile in style with the SISU 3D Mouthguard — a performance-driven lacrosse essential that blends low-profile comfort with pro-level protection. Ultra-Thin 2.0 mm Design: At just 2 mm thick, this mouthguard offers maximum comfort, effortless breathing, clear speech, and easy hydration mid‑game. Pre‑formed for Fast Fit: The ready-to-mold shape reduces boil time and ensures a snug, custom feel in under five minutes. Variable Thickness Layers: Thin inner wall for comfort and thick outer wall for protection, offering a smart balance of form and function. Perforated Breathability: Strategically placed holes keep airflow high so you can talk, breathe, and stay in communication during box lacrosse drills. Remoldable Up to 20×: Durable thermo‑polymer lets you re‑fit the guard as your teeth shift — great for growth or braces adjustments. Braces-Compatible: Youth and adult sizes (with a dentist’s help) ensure braces-friendly protection for young box lacrosse goalies. Designed to fit all standard mouth sizes, it's a reliable companion for field players, defensemen, and box lacrosse goalie gear alike. Always boil-fit before the first use, then periodically check for fit as needed. Available in various colours.
