Thanks to the smart patented magnetic buckle, you can easily open and close the safety strap under your helmet with one hand. This closure is not only easy to use, but also very safe. In addition, this Smart Bicycle Helmet is equipped with CRNK easy divider. With this adjustment system you can easily adjust the length of the safety straps so that they meet exactly under your ears. All CRNK helmets are manufactured via an In-Mold production process. This modern and complicated production method offers the following advantages compared to other helmets: Lightweight and Comfortable: In-Mold helmets are made by melting the shock-absorbing inner layer directly into the hard outer shell. This process creates a lighter helmet, which contributes to comfort, especially during extended use. Improved Shock Absorption: By integrating the inner and outer shells, CRNK In-Mold helmets provide better shock absorption. This improves protection in the event of an impact. Compact Design: All CRNK helmets have a sleeker and more streamlined design than traditional helmets with a separate hard shell and shock-absorbing layer. Durability: Although In-Mold helmets are light, they are also surprisingly durable. The one-piece construction means fewer weak points that can break or tear. Better Ventilation: CRNK In-Mold helmets have better ventilation due to their design and lightweight construction, which contributes to comfort during physical activities.
