ION Slash Amp Helmet
Description
Description
The Duotone Slash Amp sets a new standard for fit and safety with the innovative 360°-Fit system. While traditional helmets typically only adjust at the back, the Slash Amp’s adjustable band runs all the way around your head. This means the helmet adapts to your individual head shape along the entire circumference, instead of just pressing your forehead against the front of the helmet shell.
This system results in superior wearing comfort and ensures the helmet stays exactly where it should – whether you’re sailing at high speed or experiencing a hard crash. The even pressure distribution minimizes “hotspots,” and the wide adjustment range makes it possible to cover all head sizes with only two helmet sizes. The Slash Amp also features integrated ear pads that provide extra protection for your ears against both wind and impacts.
- 360°-Fit System: Fully enveloping fit that follows the natural shape of your head.
- Increased Comfort: Even pressure distribution without uncomfortable pressure points.
- Maximum Stability: The helmet stays securely in place and reduces movement during sailing and crashes.
- Integrated Ear Pads: Protect your ears from water impacts and cold wind.
- Flexible Size: The wide adjustment band means two sizes cover all needs.
- Ready for Action: Delivers a perfect “out-of-the-box” fit from your first session.
