Additionally, the product is free from harmful substances such as BPA, BPS, latex, PVC, and phthalates, assuring parents of its non-toxic nature.

However, the thin design, while promoting breathability, might not provide the level of protection some parents expect from thicker options. Cleaning is relatively easy due to its smooth surface, though it's essential to maintain regular hygiene practices. It’s especially suitable for kids under 5 feet tall, making it a specialized choice for younger athletes.

Additionally, the mouth guard includes 3D CUSH PADS and a FightGuard Insert to reduce impact energy, thus offering advanced safety for combat sports like boxing, MMA, and wrestling.

Breathability is another strong point, as it allows for maximum oxygen flow, which can improve athletic performance. The ease of cleaning is a practical aspect, given the chew-resistant high-quality material. However, it's important to note that this specific model is not suitable for kids with braces, and the fighting size is recommended for users taller than 5’1”.
