FULL-ON FUN
Mountain biking is a demanding sport – compromises and shortcuts when it comes to gear are never a good idea. The 4Forty is built to withstand the rigors of a trail riding life; with generous ventilation, the comfort of Float Fit and built-in Sweat Guide, extended rear coverage, a full hard-shell, adjustable visor, and the option of integrated MIPS protection. Boasting the comfort, protection and capable features of helmets costing twice as much, the 4Forty is an all-conditions, all-kinds of trail champion.

📏Helmet Size Chart
Measure your head circumference with a soft tape ~3 cm above your eyebrows, around the widest point at the back of your head. Match the cm value to your helmet’s size band on the product page.
Match Size
Compare your cm number to the size band on the product page (e.g. 54–58 cm). If you fall between bands, size up.
Adjustable Dial
Once on, turn the rear adjustment ring until snug. The chin strap should sit flat with no slack — fine-tune the V-yokes around your ears.
✓ How it should feel
Snug all the way around. Doesn’t move when you shake your head. Sits level — front rim about a finger above the eyebrows. No pressure points after 10 minutes.
✗ How it should NOT feel
Tilts forward or back. Slides side-to-side. Pinches the temples or forehead. Compresses ears. Has a gap between rim and forehead.
