Every Sweet Protection chart below is verified against the brand's official sizing, and all numbers are head circumference — a body measurement, in cm and inches.
Sweet Protection fit — the short version
Master chart applies across the road and trail bike line: Falconer 2Vi MIPS, Falconer Aero, Tucker / Tucker III 2Vi MIPS, Fluxer MIPS, Bushwhacker II MIPS, Chaser, Dissenter, Trailblazer.
Sweet Protection's Occigrip dial-in system covers the full range within each size band.
Outrider / Outrider MIPS uses a different chart with intentional overlap: S = 52–55 cm, M = 54–58 cm, L = 58–61 cm. Verify on Outrider product pages specifically.
Some retailers dual-label sizes as S/M, M/L, L/XL — these are the same physical shells as S, M, L. Use Sweet Protection's S / M / L convention.
Helmets
S — head circumference 53–56 cm (20.9–22.0 in)
M — head circumference 56–59 cm (22.0–23.2 in)
L — head circumference 59–61 cm (23.2–24.0 in)
Common questions
Which Sweet Protection helmet size am I? Measure your head circumference and match it to the chart: S 53–56 cm, M 56–59 cm, L 59–61 cm. Sweet Protection's Occigrip dial-in system covers the full range within each size band.
Does the Outrider use the same chart? No. Outrider and Outrider MIPS use a chart with intentional overlap: S 52–55 cm, M 54–58 cm, L 58–61 cm — verify on the Outrider product pages. Retailers that dual-label sizes as S/M, M/L or L/XL are selling the same physical shells as S, M and L.
