This may not be the burliest or lightest helmet out there but the fit and comfort are awesome. Everybody has a different shaped head and mine is a bit small for a guy and I'm wearing a m/l. With HucknRolls return policy you can always exchange sizes. I did a head over heals at Whistler last week landing on my head and it held up great as did my skull. I was so happy with the fit i ordered a poc receptor flow as well and its great too. The only reason I gave it 4 vs 5 stars was the list price but thanks to huck n Roll I got it on sale.
