DetailsLight-weight means efficient: The newly developed uvex JAKK+ ski helmet is the first, remarkably light-weight, hard shell helmet for freeriders that does not compromise safety and stability. It flies by any of its competition with some ingenious special extras. The newly designed interior with the patented octo+ adaptation system attaches itself firmly to your head and adapts automatically. A new ventilation solution between the helmet and goggle, ensures clear vision all day. Special ventilation channels draw fresh air into the helmet over the custom-made uvex goggles, making fogging up impossible.
