Fox V Core Helmet vs Alpinestars SM3 Solid Helmet

Both are DOT-certified motocross helmets with rotational-impact protection and a breakaway visor. The Alpinestars SM3 is the better pick for most riders: it adds ECE certification, weighs less in the same size, has more vents, and carries a 4.8 rating from 364 owners. The Fox V Core is a solid, simpler option with a double D closure and a wide spread of shell and EPS sizes, but it lacks ECE certification and is heavier.

• Choose the Fox V Core if you want a straightforward Mips motocross helmet with a double D strap and a precise fit across many shell sizes.
• Choose the Alpinestars SM3 if you want a lighter helmet with both DOT and ECE certification, more venting, and a strong record with owners.
