The Skate Helmet is an ideal choice for protecting your true "thinking cap" during casual, training or long endurance skating sessions. The modern and lightweight design makes it especially good for those wanting a minimalistic helmet with great features. In-mold technology helps make the helmet lighter and more breathable due to the more complex shaping of the vents. The 18 strategically shaped vents keep the air flowing through the helmet for staying as cool as possible. The Skate Helmet is also very comfortable with its internal padding and the quick and easy adjustment mechanism to enable skaters to quickly lock in on the correct size for optimal fit. Quality helmet which is sure to provide solid protection and performance. Sizes (cm) M(54-58); L(58-62)
