Giro Atmos Helmet - Bicycles

This groundbreaking fit system provides an entirely unique user experience with an unmatched level of comfort, stability, adjustability and weight savings.

With the Giro Atmos' Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the dial for a tighter feel on rough terrain, then back it off a notch and relax across the flats or a warm climb.

Micro Dial: The heart of Roc Loc 5 is this ratcheting, micro-adjusting dial. A simple, two-finger twist of the Micro Dial opens or closes the retention system and each click is audible. Three-Position Bracket: It's never been easier to change vertical positions and fine-tune fit. We incorporated a three-position bracket that features 15-millimeters of up/down movement.

The Giro Atmos Helmet is fantastic styling and exposed I.C.R. carbon fibre detailing Advanced five piece hardbody moulding In-mould technology fuses the liner with the shell and creates a true exo-skeleton, adding strength and durability to the helmet 26 Wind Tunnel design vents and internal cross-rib-channelling draw air through the helmet for excellent cooling whilst riding RocLoc 5 fits like a glove allowing lateral and vertical adjustment.
