I have a large head with a narrow profile and a generally oval shape, a pretty much worst case scenario for fitting a helmet. The Prevail takes care of this nicely, mostly eliminating the excess gap on the side of my previous size L helmet from another brand, while giving adequate clearance front and rear. For the first time ever, I have a helmet that both fits snugly and allows me to comfortably wear a skullcap underneath. Hopefully I never have to find out how it fits in a crash but it's absolutely less likely to flop up and expose my forehead due to this fit, which is a problem I've had on two occasions with other helmets designed for more circular heads than mine.

Had the worst crash of my life 6 weeks ago! fractured vertebrae in neck, compressed 3 vertebrae in back, broke 5 ribs with 2 displaced and collarbone took a plate with 12 screws and bone graft to put back together. Helmet was broken and i ended up with a small bruise and tiny cut on head where helmet hit the ground. Definitely will get another one of these helmets before i'm able to get back on bike.

I came on here to buy second one of these helmets. I'm currently in hospital after surgery on my arm. I crashed, the helmet broke, but it did its job. The only part of me that's not cut, broken or bruised is my head! This helmet simply works.

I used this helmet for sometimes. Got into an accident, got 2 brain injuries. Doctors examined and said your brain survived due to helmet. I can say it with confidence that it is one of the safest helmet in the market. Apart from safety, it looks cool and perfect feeling for ride.

Great Helmet, highly recommended

I was in a minor crash this last weekend and when my head hit the pavement it felt like it hit a pillow. Very thankful I had this helmet on. The one issue I have is the straps that go by the ear not being adjustable but overall great helmet. Will be looking into the warranty replacement program since I’ve only had it a couple months.

Not sure how cool it is in summer, I used it about 8 times in Colorado’s late winter. It is light, which is what I thought I was looking for. It protrudes high above my head which made me hesitate on keeping, but I thought it might help provide protection in a crash. Now I feel that cables that hold it together and the tall profile make excessive noise while descending. The pads, which are slightly oversized, have started coming off, just after the return window closed. More are on the way, but may need trimming to prevent them coming off. I’ll be looking for a more aero profile like I’ve seen on riders from England.

Comfortable, light weight, adjustable although chin strap adjustment is not the best around the ears if you have a small head / or are female. My last one ( which was new) saved my head when a motorcycle crashed into my rear wheel. Damaged helmet hence this replacements , but I was OK!

It's nice this classic helmet now has the upgraded MIPS system in it.

It’s a great helmet.
