Description

Designed for all-mountain adventures, the Giro Tenet MIPS Women's Helmet 2026 combines cutting-edge protection with lightweight versatility. Its hybrid construction pairs an in-mould lower shell for reduced weight with a durable hard-shell upper, offering the ideal balance of comfort, mobility, and long-term durability. Powered by MIPS® technology, the Tenet helps reduce rotational forces during certain impacts through Giro’s unique two-part design. When the weather shifts, Thermostat Control™ Adjustable Venting lets you fine-tune airflow for the perfect temperature. Complete with the In Form 2 Fit System for quick, precise adjustments and breathable Ionic+® Fleece for lasting freshness, the Tenet ensures a personalized fit and superior comfort.

Features:

IN FORM 2 FIT SYSTEM — The In Form 2 Fit System is lighter and lower-profile than the original, and easier to dial in a custom fit in seconds — even with gloves on. An improved dial design provides up to 6cm of adjustment plus enhanced stability.

THERMOSTAT CONTROL — Thermostat Control Adjustable Venting allows you to custom-tune airflow instantly with a simple, low profile control button on the outside of the helmet. No other system is faster or easier to adjust, and nothing is more effective at keeping you comfortable.

VERTICAL TUNING — Accommodates different goggles and head shapes for a custom fit free of gaper gap

IONIC+® PADDING — Pure silver is the secret ingredient that gives IONIC+ ® the power to provide natural, permanent odour protection to keep your helmet feeling fresh.
