Giro Tenet MIPS Snow Helmet for Men, Women & Youth - Brim Style

In this review we test the Giro Tenet MIPS snow helmet to see who will get the most value from its protection and comfort features. The bottom line: the Tenet is aimed at all-mountain riders who want a lightweight, durable helmet with adjustable ventilation and an easy-to-dial fit system. The single biggest reason to buy is its hybrid construction paired with integrated Mips, which balances low weight and increased impact protection for a wide range of skiers and snowboarders.

Key Features

• Hybrid Construction: A hard-shell upper combined with an I.M. lower shell and sidewalls provides enhanced durability where you need it while keeping overall weight down.
• Integrated Mips: The two-part construction is designed to reduce rotational energy in certain impacts, improving safety on unpredictable falls.
• In Form 2 Fit System: The lighter, lower-profile dial lets riders fine-tune fit quickly and securely, even while wearing gloves.
• Thermostat Control venting: External, low-profile control lets you open or close vents on the fly to regulate temperature without removing the helmet.
• Ionic+ Fleece: Breathable fleece lining adds comfort and moisture management for long days on the hill.

Who It's For

The Tenet is best for all-mountain skiers and snowboarders-men, women, and youth-who prioritize a helmet that is both durable and lightweight for long sessions. Riders who value adjustable ventilation and a simple, reliable fit system will appreciate the practical controls and comfort features.

Those who want the absolute lightest touring-specific shell or a fully vented summer helmet for warm-weather ski training should look elsewhere; the Tenet balances protection and ventilation rather than pursuing minimal weight at all costs.
