This type of helmet combines breathability with the flexibility of installation accessories to ensure that rescuers can work safely and comfortably in complex water environments;

[0003] This type of water rescue helmet has multiple ventilation holes on its outer surface, which can effectively discharge the heat and moisture generated by the head, reduce the rescuers' feeling of stuffiness, and improve comfort. The mounting net can more conveniently install tactical accessories such as night vision goggles, lighting, communication equipment, etc. to meet the needs of different rescue missions.

[0004] However, if this water rescue helmet with a net installed under the air vents is used in a rainy environment, rainwater from the outside will flow into the interior of the helmet through the air vents, eventually causing water accumulation inside the helmet or water flowing into the eyes, causing inconvenience and safety hazards to the rescue operation; therefore, the existing needs are not met, and we propose a water rescue helmet with a net installed under the air vents. Utility Model Content
