GIRO TENET MIPS winter helmet — size L (59–62.5 cm), matte black, MIPS protection

The GIRO TENET MIPS winter helmet in matte black, size L (59–62.5 cm), is a cold-weather protective helmet engineered for cycling and outdoor activities. It combines a multi-layer impact-absorbing shell with integrated MIPS technology to reduce rotational forces during impacts. The helmet is designed to accept winter liners and to provide stable fit and compatibility with eyewear, making it a practical choice for riders who need protection and comfort in low temperatures.

Advantages

The helmet provides rotational impact protection through the MIPS system while maintaining a low-profile matte finish that resists glare. Its construction balances impact absorption with ventilation tailored for cold-weather use, and the adjustable retention system ensures a secure fit for head circumferences in the 59–62.5 cm range. The design supports compatibility with winter liners and goggles, improving thermal comfort and eyewear integration.

Suitable for

• Road cycling and commuter rides in cold or wet conditions
• Gravel and light off-road winter rides
• Urban cycling where additional head protection and eyewear compatibility are needed
• Outdoor activities that require insulated helmet coverage and impact mitigation

When it may not be suitable

This helmet is optimized for winter and cold-weather use; it may be less comfortable in hot climates due to its insulation and reduced ventilation compared with summer-specific helmets. Riders who need the highest level of aerodynamic performance for competitive racing or who require a very lightweight summer helmet may prefer a model specifically designed for those purposes.

Key specifications

• Size range: Large fit for head circumference 59–62.5 cm
• Color: matte black finish
• Protection system: integrated rotational-impact protection (MIPS)
• Construction: impact-absorbing shell designed for cold-weather use
• Fit: adjustable retention system for secure fit
• Compatibility: supports winter liners and eyewear/goggle integration

How to use

Measure your head circumference to confirm the Large size fits within 59–62.5 cm, then adjust the retention system so the helmet sits level on the head with the front edge approximately two finger-widths above the eyebrows. Fasten the chin strap and tighten until snug but comfortable, ensuring straps form a V-shape below each ear. When riding in cold weather, install an appropriate winter liner if desired and position eyewear or goggles to interface with helmet vents and the brim without obstructing vision.

What to consider before purchase

• Confirm head circumference falls within the 59–62.5 cm fit range
• Consider whether you need enhanced ventilation for warmer conditions
• Check compatibility with your preferred winter liners and eyewear
• Verify that the matte black finish meets your visibility or styling preferences

Usage recommendations

Use the helmet for winter cycling and outdoor activities where rotational protection and insulation are priorities. Regularly inspect the shell and retention components for damage, and replace the helmet after any significant impact. Clean with mild soap and water and avoid solvents that can degrade materials.
