DESCRIPTION
Only Giro could engineer an impressively lightweight full-face helmet that still provides heavyweight protection. At a mere 800 grams in medium, this NTA-certified MTB helmet still packs the punch of Spherical Technology™, powered by Mips®, sandwiching our innovative integration of Mips in between independent EPP and EPS foam layers designed to optimize management of both high-speed and low-speed impacts. Coalition Spherical also manages to rival the ventilation and cooling power of some brand’s road helmets, pairing massive front intake ports with efficient rear exhaust vents via deep internal channeling.
Like many of our creations, one of Coalition’s most impressive innovations lies hidden inside: the Halo
System combines a chinbar with Pebax® (a material that is engineered to provide the perfect range of flex and rigidity) and elastomeric bushings that are integrated into the EPS to absorb and dissipate kinetic forces. The result is a helmet that exceeds standard chinbar deflection certification testing by almost 2x.
With Ionic+™ treatments to control odor, and two sets of removable cheek pads to help fine-tune fit, the Coalition Spherical sets a new benchmark for lightweight full-face protection.

SIZE INFORMATION
BIKE HELMET SIZE GUIDE
HOW TO MEASURE YOUR SIZE
Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide.
Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.

MEASURING YOUR HAND FOR THE BEST FIT
You can measure the length and width of your hand as illustrated above, and use the Size Guide to determine your size.
1. Wrap the tape measure around your hand at the widest part of the palm, and lightly close your hand to get your Hand Width measurement.
2. Once you have that measurement recorded, use a tape measure to determine the length of your hand from the tip of your longest finger to the base of your palm at the wrist. This is your Hand Length measurement.
3. You can then compare the measurements of your hand with the data supplied in the Size Guide to determine the best fitting size for you.
