Great Fit, Comfort & Protection at a Solid Price!

The Fox Racing Mainframe helmet is an excellent choice for mountain biking, offering top-notch protection at a reasonable price. The MIPS technology provides added safety, giving me peace of mind on technical trails. It’s lightweight and super comfortable, with plenty of ventilation to keep me cool on long rides. The fit is spot on—the adjustable retention system makes it easy to dial in for a snug, secure feel without being too tight. Plus, it looks great and has that signature Fox Racing style that stands out on the trails. For the price, you’re getting premium features that are usually found in more expensive helmets. Highly recommend for anyone looking for quality, comfort, and protection without breaking the bank!

Well done Fox!

Great helmet with MIPS protection. Perfect for my 13 year old. I may grab one for myself. Excellent breathability, nice strap that’s easy to take on and off, but secure and love the bill for extra son protection on the face. Fits well with sunglasses as well when riding. Enjoy!

Buen casco

Está súper bueno, tiene su almohadillas para el sudor de respuesta; pero no tiene funda para guardarlo. Debería tenerlo por la calidad.
