Compatibility with goggles and dedicated audio accessory integration supports convenience and functionality on the slope.

Suitable for

• Alpine skiing where standardized impact protection and fit adjustability are required
• Recreational skiers who want certified head protection and multi-impact performance
• Riders who use goggles and may want to add audio accessories without sacrificing fit
• Skiers seeking a neutral matte white helmet that fits head sizes 55.5–59 cm

When it may not be suitable

This helmet may not be suitable for users whose head circumference falls outside the 55.5–59 cm range, as a secure fit is essential for protective performance.

How to use

Place the helmet on the head and adjust the internal fit system until the helmet sits snugly and evenly around the head without pressure points. Fasten and adjust the chin strap so it sits comfortably under the chin and allows normal jaw movement while keeping the helmet stable. Position ski goggles so they mate with the helmet’s goggle interface without leaving gaps; if using audio accessories, install them according to the accessory instructions and confirm they do not interfere with fit or retention. Regularly inspect the helmet for visible damage and replace it if it sustains a significant impact or shows signs of thinning or cracking.

What to consider before purchase

• Measure head circumference to ensure it falls within 55.5–59 cm for correct sizing
• Confirm intended use is alpine or recreational skiing to match the helmet’s certification and design
• Check compatibility of any third-party audio accessories with the helmet’s integration features
• Consider shell finish and color (matte white) for visibility and aesthetic preferences

Usage recommendations

Use the adjustable fit system and padding to achieve a stable, comfortable fit before each session on the slopes. Replace the helmet after any significant impact or if you notice structural damage. Pair the helmet with properly fitting goggles and approved audio accessories to maintain protection and comfort while skiing.
