Giro Tenet MIPS Snow Ski Helmet - Lightweight All-Mountain

Our review of the Giro Tenet MIPS finds it best suited to skiers and snowboarders who want a lightweight, adjustable all-mountain helmet with upgraded rotational protection. The single biggest reason to buy is the combination of Giro's hybrid construction and integrated Mips, which delivers a durable hard-shell upper, a lighter I.M. lower, and a slip-plane system intended to reduce certain rotational forces on impact. The Tenet balances comfort and safety with a low-profile fit and easy on-the-fly venting, making it a solid choice for long days on varied terrain.

Key Features

• Hybrid Construction: A hard-shell upper combined with an I.M. lower gives a durable exterior while keeping overall weight down for all-day comfort.
• Integrated Mips: The two-part construction includes Mips to help reduce rotational energy in certain impacts for added protection over standard helmets.
• In Form 2 Fit System: The updated dial is lighter, lower-profile and offers up to 6cm of adjustment so the helmet is quick to fine-tune, even with gloves on.
• Thermostat Control: Adjustable venting uses a low-profile external control to tune airflow instantly as weather or exertion changes on the hill.
• Ionic+ Fleece Lining: Breathable fleece improves comfort against the head and helps regulate temperature with a soft, insulating layer.

Who It's For

The Tenet is aimed at recreational to aggressive all-mountain riders who want a helmet that performs across groomers, trees and moderate off-piste runs while remaining light and comfortable for long sessions. Its combination of a tough hard shell and lighter lower shell suits skiers and snowboarders who value durability without the bulk of full hard-shell designs.

Riders seeking an ultralight backcountry-specific touring helmet with integrated weight-saving features or those who require extremely high ventilation for race-style use may prefer a purpose-built touring or race helmet. Similarly, riders who want a minimalist fashion-forward lid without external venting controls should look elsewhere.

Pros & Cons

Pros

• Strong protective approach from hybrid hard-shell and EPS liner while keeping weight manageable.
• Integrated Mips adds a layer of rotational protection that can reduce certain forces in impacts.
• Easy, precise fit with the In Form 2 Fit System and a comfortable Ionic+ fleece liner.
• Thermostat Control venting is fast and simple to adjust on the fly for changing conditions.

Cons

• Slightly heavier than the lightest in-mold only helmets because of the hard-shell upper, which may matter to weight-conscious tourers.
• Design and venting control add external complexity for riders who prefer minimalism.
