In 2010, GY developed GY-PH9000 series ice hockey helmet. Thirteen years later, in 2023 we are happy to announce that our brand-new GY-PH9000D series ice hockey helmet will launch in November 2023. Made of D3O protective material, the inner lining of this series of ice hockey helmets is made using state-of-the-art 3D lattice printing technology, which is extremely protective, breathable, and comfortable.
