Winter helmet GIRO Jackson MIPS, matte stone, size L (59–62.5 cm), model 2025/2026

The GIRO Jackson MIPS winter helmet in matte stone, size L (59–62.5 cm), is a protective helmet designed for alpine skiing and snowboarding. It integrates MIPS rotational impact protection with a hard outer shell and impact-absorbing liner to manage linear and rotational forces. The helmet is sized to fit head circumferences from 59 to 62.5 cm and includes features for adjustable fit, ventilation, goggle compatibility and optional audio accessory integration, providing a balance of safety, comfort and on-slope functionality for winter sports participants.

Advantages

The helmet combines rotational-impact mitigation technology with a durable outer construction and a comfort-focused inner liner, delivering consistent protection during downhill skiing and freestyle use. An adjustable fit system allows fine-tuning to individual head shape, while integrated vents and a matte stone finish offer a neutral aesthetic and breathability during active use. Compatibility with goggles and audio accessories increases versatility for different riding styles.

Suitable for

• Alpine skiing at resorts and backcountry approach where a certified helmet is required
• Snowboarding, including park and freeride where rotational protection and a secure fit matter
• All-day slope use when a balance of protection, ventilation and comfort is needed
• Riders who use goggles and want headset/audio accessory compatibility

When it may not be suitable

This helmet is optimized for alpine skiing and snowboarding and may not be appropriate for non-snow sports such as cycling, motorized activities or industrial safety tasks that require different certification and construction. If you need a very compact or ultra-lightweight helmet for occasional use, a specialized low-profile model may be a better fit than this winter-specific design.

Key specifications

• Size range: designed to fit head circumferences approximately 59–62.5 cm
• Protection technology: rotational-impact mitigation system integrated into helmet structure
• Shell: hard outer shell with energy-absorbing inner liner for impact management
• Fit system: adjustable retention for personalized fit and stability
• Ventilation: integrated vents to manage airflow and temperature during activity
• Goggle compatibility: shaped ear and brim areas for secure goggle integration
• Accessory compatibility: provisions for audio accessories in ear pockets or attachment points

How to use

Measure head circumference and set the helmet to fit snugly at the size range indicated. Position the helmet level on the head, with the front edge above the eyebrows, and fasten the chin strap so it is snug but not restrictive. Use the adjustment dial or retention system to eliminate wobble while allowing comfortable movement. Pair the helmet with compatible goggles, routing straps into the intended goggle channel, and install audio accessories according to the accessory manufacturer’s instructions. Inspect the helmet before each use for cracks, compression of the liner or damaged straps, and replace the helmet after significant impact.

What to consider before purchase

• Confirm your head circumference falls within the 59–62.5 cm size range for size L
• Verify that the helmet meets local safety standards required for alpine skiing and snowboarding in your region
• Consider whether integrated ventilation and the matte finish meet your comfort and style preferences
• Check compatibility with your goggles and any audio accessories you plan to use

Usage recommendations

For best protection, replace the helmet after any significant impact, store it away from extreme heat and solvents, and maintain clean, dry liners. Adjust vents and layers to match activity intensity and weather conditions to maintain comfort while ensuring continued protection on the slopes.
