Description

Designed for all-mountain adventures, the Giro Tenet MIPS Helmet 2026 blends lightweight performance with rugged durability through its hybrid construction—combining an in-mould lower shell for reduced weight and a hard-shell upper for long-lasting strength. The result is exceptional comfort and freedom of movement, season after season. Made with MIPS® technology, the Tenet helps reduce rotational energy during certain impacts, offering advanced protection when you need it most. To handle changing conditions, Thermostat Control™ Adjustable Venting allows you to fine-tune airflow for ideal temperature regulation. Meanwhile, the In Form 2 Fit System provides quick, precise adjustment, and the breathable Ionic+® Fleece lining ensures lasting 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.
