Giro Womens Avera MIPS Snow Helmet, Matte White (Limited), Size Medium, Thermostat Control

The Giro Avera MIPS Women's snow helmet is a lightweight, women's-specific alpine helmet with integrated MIPS rotational protection, adjustable Thermostat Control venting and an easy In Form Fit dial for a custom size M fit (55.5–59 cm).

Designed for skiers and snowboarders who want a balance of safety, comfort and quick on-mountain adjustability, the Avera combines a rugged two-piece hard shell with a lower polycarbonate wrap, a slim profile for goggle compatibility, and subtle styling in a limited matte white finish. The helmet packs features aimed at everyday riders: a MIPS slip-plane to address rotational forces, a fast external venting control, and a fit system that can be tuned even with gloves on.

How does this helmet manage impact and rotational forces?

The Avera uses Giro's Integrated MIPS system to add an inner slip-plane that helps reduce rotational energy transmitted to the head during oblique impacts. This MIPS layer is built into the helmet's fit system so it works with the shell and liner rather than as an aftermarket add-on. Giro engineers the shell and liner to meet strict safety standards while keeping weight down for prolonged comfort on the hill.

• Integrated MIPS slip-plane combined with the helmet's adjustable fit system
• Durable two-piece hardshell with a polycarbonate lower wrap
• Designed to meet and exceed standard helmet safety tests

How do the vents and Thermostat Control help when conditions change?

Thermostat Control offers an external, low-profile button that opens or closes ventilation instantly so you can regulate airflow without removing gloves. The system makes it fast to adapt to warming midday sun or a sudden temperature drop, keeping you comfortable while you ride. Vents are channeled through the liner to move heat away efficiently.

• One-touch Thermostat Control for rapid vent adjustment
• Vent channels that promote steady airflow through the liner
• Simple operation suitable for gloved hands

Will this helmet fit my goggles and remain comfortable all day?

The Avera is made with a seamless goggle interface and women's-specific styling to reduce pressure points and work well with a variety of ski and snowboard goggles. Giro's In Form Fit System provides up to 6 cm of adjustment via an ergonomic dial, giving a secure, centered fit that can be fine-tuned on the run. The result is stable helmet placement and better goggle integration without extra bulk.

• In Form Fit dial gives quick, precise sizing adjustments
• Vertical tuning and women's-specific internal shaping for improved comfort
• Seamless compatibility with Giro ski and snowboard goggles

What materials and construction make this helmet durable yet lightweight?

The Avera uses a bonded two-piece hard shell construction: a tough outer layer fused to a polycarbonate lower wrap that increases impact resistance without adding unnecessary mass. This I.M. Hardbody lower wrap protects the liner edge and contributes to a compact silhouette. Internal liners and trim are chosen for comfort and moisture management during long days on the mountain.

• Hard shell fused to polycarbonate lower wrap for durability
• Compact profile minimizes bulk while preserving protection
• Comfort-focused liner materials for heat and sweat control
