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

The GIRO TENET MIPS matte white, size M (55.5–59 cm), is a winter protective helmet created for snow sports and cold-weather cycling. It combines a hard outer shell with impact-absorbing liner materials and the MIPS rotational-force mitigation system to reduce rotational energy transfer during oblique impacts. The helmet includes adjustable fit features and ventilation designed to balance warmth and airflow for use in variable winter conditions.

Advantages

The helmet offers integrated rotational protection through the MIPS liner, helping to reduce rotational forces in angled impacts. Its construction delivers impact energy management with a comfortable internal liner and an adjustable retention system for a secure fit in the 55.5–59 cm head-size range. The matte white finish is easy to clean and provides neutral styling for diverse winter outfits and gear.

Suitable for

• Recreational downhill skiing and snowboarding
• Commuting or cycling in cold-weather conditions
• All-mountain and resort use where warmth and protection are needed
• Riders and skiers seeking a helmet with rotational protection technology

When it may not be suitable

This helmet is sized for medium head circumferences (55.5–59 cm) and will not fit smaller or significantly larger heads comfortably. It is designed for winter sports and cold-weather cycling; for road cycling in warm conditions or for specialized disciplines that require highly ventilated road helmets, a dedicated road helmet may be more appropriate.

Key specifications

• Intended use: winter sports and cold-weather cycling
• Fit range: medium (55.5–59 cm)
• Safety feature: rotational-force mitigation system (MIPS)
• Shell finish: matte white
• Retention: adjustable fit system for secure fit
• Ventilation: designed for balanced warmth and airflow in cold conditions

How to use

Place the helmet on the head so it sits level and covers the forehead without tilting backward. Adjust the retention system until the helmet feels snug but not tight, and fasten the chin strap with its buckle, leaving enough room to fit one or two fingers between the strap and the chin. Use the available vents and any removable liners or ear pads according to ambient temperature: add liners or close vents in very cold conditions for more warmth, and open or remove them when activity increases to manage moisture and temperature. Inspect the helmet before each use for visible damage and replace it after a significant impact or if structural damage is found.

What to consider before purchase

• Confirm head circumference matches the 55.5–59 cm fit range for size M
• Decide whether the integrated MIPS rotational protection meets your safety preferences
• Consider the level of ventilation and insulation you need for your typical winter activity
• Ensure the helmet style and matte white finish meet your visibility and aesthetic needs

Usage recommendations

Use this GIRO TENET MIPS helmet for winter sports and cold-weather cycling where combined impact protection and rotational-force mitigation are desired. Regularly check fit and condition, replace the helmet after a significant impact, and pair it with appropriate winter accessories such as goggles and a neck gaiter for complete cold-weather protection.
