  • 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! ... show more

  • 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!

  • Great fit second time
Size: Medium Color: TRVRS - Flo Yellow
Bought first one and it was larger than expected so returned it for a smaller size. Fits great, comfortable, and well ventilated. Happy with purchase. Color is bright too which is helpful on the street and trails.

  • Great Mountain Biking Helmet
Size: Large Color: TRVRS - Flo Red

  • Good enough fit
Fit like it should, could use a little more padding

  • Great value for the money
The helmet is so comfortable I forget I’m wearing it most of the time. The build quality is great and if you can get it on sale this is a fantastic value for the money from a name brand manufacturer. It also ranks decently by independent helmet test facilities. I like it so much I got another one for the wife. ... show more

  • Works great in a crash
I purchased this helmet, wore it twice and crashed hard on my mountain bike, landing on my head. I escaped with no head injuries, and bought the exact same helmet immediately after the crash. (You're supposed to throw away your helmet anytime it takes a hard impact) Wasn't happy about buying the same product twice in 2 weeks but it's such a good value, and it saved my head, so I had no problem making the decision to rebuy it. ... show more
