Warrior Alpha One Pro Hockey Helmet — pro helmet with TRUE One Shell, OmniShock+ with Viconic inserts and AdaptFit 270 BOA for premium fit and protection.
The Warrior Alpha One Pro Hockey Helmet is the pro helmet for the senior elite player who wants premium protection, exact fit and pro technology. With TRUE One Shell, the OmniShock+ protection system and AdaptFit 270 BOA adjustment, Alpha One Pro delivers elite-level protection for contact sports.
The TRUE One Shell construction is a one-piece manufactured high-density plastic that delivers superior stiff, strong and lightweight protection. Designed to withstand the toughest game situations — a barrier of advanced protection that doesn't flinch on contact.
The OmniShock+ protection system with Viconic inserts places lightweight cushioning in strategic zones — frontal lobe, temples and occipital. That's where the brain needs the most protection, and Alpha One Pro delivers pro-level cushioning matching elite standards.
The AdaptFit 270 BOA system delivers even fit around the entire head via micro-adjustment on a BOA dial. This is fit technology from pro snowboarding and cycling, applied to hockey to eliminate pressure points and ensure the helmet sits right every game.
Bottom line: The Warrior Alpha One Pro is the pro hockey helmet for the senior elite player. Shop Warrior hockey gear and other elite hockey equipment at MonkeySports.

Size Guide
Find the right size for Alpha One, Alpha One Pro, Covert CF 100 and Covert CF 80 — measure your head circumference for the best fit.
Wrap a soft tape measure around your head just above your eyebrows and across your temples. Measure in cm.
Measure against the scalp — not over thick hair. A lot of hair can give a misleading reading.
Take two measurements to confirm accuracy. If they differ slightly, use the larger value.
The helmet should sit flat on the head without rocking side to side. Cheek pads should rest against the cheeks without squeezing.

FAQ
Wrap a soft tape measure around your head just above your eyebrows and across your temples — the widest point of your head. Keep the tape flat and not pulled too tight. Measure in cm.
The size charts in this guide cover Senior models only. Warrior helmets are available in Junior and Youth but are sized using different guidelines — contact us for advice.
Alpha One Pro is an upgraded version with improved protection materials and fit. The size ranges are nearly identical — the Pro model has a slightly narrower Small starting point. Choose Pro if you prioritise maximum performance and protection.
Warrior helmets are adjustable within each size range. If you are between sizes, choose M and dial in the fit using the helmet's built-in adjustment ring. A helmet that is too small cannot be adjusted enough and will feel uncomfortably tight.
