Winter Helmet GIRO JACKSON MIPS – brand GIRO, model JACKSON MIPS, size S (52–55.5 cm), matte white

The GIRO JACKSON MIPS winter helmet in matte white, size S (52–55.5 cm), is a protective helmet designed for skiing and snowboarding. It integrates MIPS rotational impact technology to help reduce rotational forces during oblique impacts and features an adjustable fit system to secure a close, stable seal around the head. Ventilation is balanced for cold-weather use, and the shell and liner construction provide impact protection appropriate for winter sports.

Advantages

The helmet combines a low-profile shell with internal rotational protection to address both direct and angled impacts. The adjustable fit system allows fine tuning to the 52–55.5 cm head circumference range, improving comfort and stability during active use. Matte white finish offers a neutral, low-glare appearance that pairs with a variety of outerwear, while ventilation designed for winter conditions helps manage temperature without excessive airflow that would reduce warmth.

Suitable for

• Alpine skiing and resort skiing
• Snowboarding at pistes and terrain parks
• Frequent winter riders who need a secure, low-profile helmet
• Adults and teens whose head circumference fits the 52–55.5 cm range

When it may not be suitable

This size S helmet is not suitable for users outside the 52–55.5 cm head circumference range; an incorrect fit reduces protective effectiveness. The ventilation balance favors cold-weather comfort, so users seeking maximum airflow for high-exertion activities in mild conditions may prefer helmets with larger vents.

Key specifications

• Size range: 52–55.5 cm (S)
• Color: matte white
• Rotational impact protection: integrated MIPS system
• Fit system: adjustable rear and strap adjustments for a secure seal
• Ventilation: low-to-moderate vents optimized for cold conditions
• Intended use: skiing and snowboarding

How to use

Place the helmet level on the head so the front edge sits just above the eyebrows. Adjust the rear fit system until the helmet feels snug but comfortable, and fasten and tighten the chin strap so it rests firmly under the chin with room for one or two fingers. Inspect vents and ensure ear pads and liners are positioned correctly for comfort. Replace the helmet after a significant impact or when structural damage is visible; follow manufacturer guidance for care and storage in dry, moderate conditions.

What to consider before purchase

• Measure head circumference accurately to confirm the 52–55.5 cm fit range.
• Decide whether integrated rotational protection (MIPS) meets your safety preferences.
• Consider compatibility with your goggles and ear pad preferences.
• Check weight and ventilation needs relative to your typical activity intensity and climate.

Usage recommendations

For optimal protection and comfort, use the GIRO JACKSON MIPS helmet with properly fitting goggles, adjust the fit system before each session, and replace the helmet after any significant impact. Store the helmet in a cool, dry place away from solvents and direct heat to preserve materials and protective properties.
