Winter Helmet GIRO JACKSON MIPS – size M (55.5–59 cm), matte white

The GIRO JACKSON MIPS winter helmet in matte white (size M, 55.5–59 cm) is a protective helmet designed for alpine winter sports such as skiing and snowboarding. It combines a low-profile shell with integrated rotational impact protection to reduce rotational forces in certain impacts. The helmet is intended to fit medium head sizes and provides coverage and retention features suited to winter use.

Advantages

The helmet integrates MIPS rotational protection technology to address rotational forces during angled impacts. Its matte white finish offers a neutral, low-glare appearance while the medium shell size is shaped to balance coverage and mobility. The design includes adjustable retention to improve fit stability and internal padding suitable for cold-weather wear.

Suitable for

• Alpine skiing and ski touring on groomed pistes
• Snowboarding on piste and park riding where a medium-size helmet is appropriate
• Recreational winter sports where impact protection and head coverage are required

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; an incorrect fit reduces protective performance. It is not designed or certified for non-winter sports such as cycling or motorized vehicle use unless explicitly stated by the manufacturer.

Key specifications

• Intended use: winter sports (skiing, snowboarding)
• Size range: medium fit for 55.5–59 cm head circumference
• Protection technology: rotational impact mitigation system (MIPS)
• Shell finish: matte white
• Fit system: adjustable retention for secure fit
• Inner padding: cold-weather comfort padding (removable or fixed depending on model)

How to use

Place the helmet on the head so it sits level and covers the forehead without tipping back. Adjust the retention system until the helmet fits snugly but comfortably; straps should form a V under each ear and the chin strap should fasten securely with one or two fingers’ space for comfort. Ensure any removable liners are correctly positioned and that vents (if present) are set according to personal comfort. After any significant impact, replace the helmet or follow the manufacturer’s inspection guidance.

What to consider before purchase

• Accurate head measurement within the 55.5–59 cm range to confirm medium size fit
• Compatibility with goggles and other headwear such as balaclavas or ear pads
• Requirement for rotational protection technology (MIPS) and shell finish preference
• Whether the helmet’s fit system and padding meet personal comfort needs in cold conditions

Usage recommendations

For reliable protection, ensure the helmet is adjusted for a secure fit before each session. Replace the helmet after significant impact, prolonged sunlight exposure that degrades materials, or according to manufacturer lifetime guidance. Pair the GIRO JACKSON MIPS with properly fitted ski goggles and follow routine cleaning and storage instructions to maintain performance.
