Are they all liars?

  • Familiarity: I returned this product before using it

It says right on the helmet 260 grams but on the scale its 305.... It IS way lighter than my old Giro Athalon which is 375 and it does seem to fit pretty well. Should I try another or just assume they all lie and will be about 300 grams regardless of what they say????
