Giro Havoc Cycling Helmet:
Good looks and secure versatility too. Giro's Havoc bike helmet gets everything right on all counts with an adjustable Roc Loc® 3 fit system and their proven In-Mold system that fuses the 27-vent shell to the liner for incredible structural integrity. The lightweight external microshell is fused to the inner EPS liner, so you'll find better durability along the Havoc's numerous vents and ribs than anything with a conventional design. The versatile Rock Loc® 3 adjustment system gives you a wider range of sizing options than the recreational Acu Loc system, so the fit is customized for your cranium. This is a great helmet for trails and steep single track, but you can also remove the snap-fit visor for a profile that's remarkably similar to Giro's road bike helmets.
