What People Are Saying

Very light and comfortable. I like the style and it was a very easy process to get fitted for this unique helmet.

Richard. _ 12/30/25

As someone who was always on the smaller side of a medium, but too large for a small, I had to put up with helmets that looked oversized and needed to be ratcheted down to stay put. This one fits so well I don’t even need the ratchet.

Lane. _ 05/13/26

It feels great throughout long rides and I even forgot to take it off after a ride recently! Do yourself a favor and order the perfect helmet - for comfort, safety, design, weight, and ventilation!

Claudia G. _ 11/06/25

I always stick to the same couple of helmet brands because I know they fit. I’m hesitant to try something new if I can’t try it on but that wasn’t the case with KAV. The process was easy and the helmet fits perfectly!

Jake. _ 04/27/26

I finally have a helmet that doesn’t look ridiculous on my head.

"This is the best helmet I’ve ever owned. Well worth the wait. Hardest part was adjusting the strap placement around my ears. Now all I have to do is put it on my head and clip the strap. No more adjusting the back closure and looking in the mirror to make sure it is not crooked on my head. Fits perfectly every time."

Love the Silvo!

"Went looking for a new road helmet. Looked at Abus and even purchased a Sweet Protection Falconer Aero. That was too tight on the sides of my head. Kept looking and came across Kav. Was intrigued by the custom Rhoan but didn't want to wait to receive the helmet. Then I saw they had just released the Silvo. Took a chance and purchased a large in black. Ordered on a Monday and received on a Thursday, great turnaround time. Tried it on and. . . . . . . . finally!!! A great looking helmet that doesn't make my large noggin look like a mushroom. The fit is amazing. It almost feels like it's custom for me. Didn't have to dial in much at all to get a perfect fit. Love the brow band and the trampoline effect that it has against my forehead. The 'pads' that Kav uses are so much better than traditional pads that soak up sweat. Also, love the finish of the helmet. I much prefer this unique texture versus the smooth plastic of traditional helmets. Add in a 5 star safety rating from VT and I've got my perfect helmet. Thanks Kav!"

Great out of the box

"After a few hundred miles I can report that this is worth the money. Vents well, looks good and fits comfortably. There is a bit of a learning curve with sweat management, but as long as it isn't running into my eyes it's fine. The turn-around was under six weeks. As someone who was always on the smaller side of a medium, but too large for a small, I had to put up with helmets that looked oversized and needed to be ratcheted down to stay put. This one fits so well I don't even need the ratchet. Custom colors are a bonus. Overall no buyer remorse (and that is after trying on every helmet at Sea Otter this year)."

Exceeded expectations and would buy it again

"I was in need of a new helmet as my Abus Gamechanger was aging out. I admit I was a bit skeptical of the 3D printed concept, but the custom sizing and crash ratings convinced me. Now that I have been riding with the helmet for a couple months now, I have to say I'm really happy with this helmet due to how it performs. The cooling vents are far superior to anything else I have ridden in the past. It's like having an A/C on your forehead in the summer. The fit is excellent and its well constructed. I like the all white colorway I was able to customize, and am pleased to not have to deal with foam pad cushions or inserts any longer. This helmet is the actual gamechanger."

Hi-Vis Nova

"Love the Hi-Vis orange! Helps to safely stand out and be seen while in traffic. Distinctive design makes this helmet a cool stand out to all the other mass produced helmets. Lots of compliments. . . and "what brand is that helmet?"

— Christian M. (5/5)

Really nice. Heaps better than the Nova.

"It's really, really nice. I wish I could give it 4. 5 stars. If you had a Nova and didn't like it, give the Rhoan a shot. It's not that much lighter, but it FEELS way lighter. The dial fit is a total game changer. A nice bonus is the brow of the helmet sticks out enough that it's almost a mini visor."

— Littlewing (4/5)

Great Investment

"Helmet fitting process was very impressive and resulted in a snug by very comfortable fit. Love the color customization. Not the lightest helmet, but you can prefer the Rhoan is weight is a big concern. The main issue I encountered was a poor communication when my order was delayed due to operational shifts to the East Coast. The delivery times on the website now (8-10 weeks) are what I encountered but when I ordered my helmet it was a 4 week estimate. This was very frustrating when the helmet took exceptionally longer than promised with no explanation or customer service number to call."

SAVED MY LIFE? WHO KNOWS

"On July 22, 2025 I was involved in a serious automobile accident while riding my bike and wearing my KAV Rhoan helmet. I was struck by a vehicle traveling in excess of 60 miles an hour while I was riding about 20 mph. I’m a lucky guy as my recovery is basically waiting for bones to heal (fractured/de-gloved right hand, broken left ankle and fibula, a couple of broken ribs, spinous process C7, pubic ramus), dislocated right shoulder, and assorted road rash. No neurological injuries, no real cosmetic damage (I’m still just as ugly as ever, but no uglier - woot woot). Every medical professional that has seen my chart and heard my story cannot believe I’m not more neurologically injured. Thanks for producing such a great helmet. I’ll be thanking myself every day for buying one."

Crash Report-A+

"Been wearing my KAV Nova for less than a year but it is the only helmet I can get to fit properly on my very long, narrow head. Loved it for it's light weight, great air flow and comfort. Last month I had a crash while training. (Can't tell you why, as I have no memory of the crash. ) Hit the ground hard on my right at about 18mph, broke my hand and 2 fingers, my nose, sunglasses, bike, and helmet. CT scan was clear and had no obvious concussion symptoms (except for memory loss). Helmet shows signs of hard hit. Outer shell dented and small cracks. Inner shell is not visibly damaged. Most importantly, it stayed in place (good fit) and my head is intact. That crash would have been FAR worse without my KAV helmet. I am replacing it with another. They get my strongest recommendation."

— Kevin P. (5/5)

Best helmet I've ever had!

"20 rides in with my new helmet and love it! The fit is perfect, much better than all the "off the shelf" helmets I've had. Great airflow and sweat is channeled off to the sides of my face, not in my eyes. Awesome customer service, too. I don't often leave reviews but was compelled to leave one this time. Great job, KAV."

— Steve P. (5/5)

Hi-Vis Nova

"Love the translucent Hi-Vis orange! Lots of comments and compliments. When I stopped by KAV. Jordan and Mike were VERY helpful in fine tuning my helmet fit. Very professional, knowledgeable and friendly. I highly recommend KAV helmets for their quality, and customer service."
