Bontrager  Starvos WaveCel Round Fit Bike Helmet

This is a perfect fit helmet for ROUND head. I am Asian and I have a very round head. I always have to go up 1 size than my head measurement for regular western market (North America, Europe) bike helmet as they are too elongated oval shape. There are always gaps in the front and back of my head when I had to go up 1 size, it was never a good fit. But since this helmet is much rounder in shape (wider in width and shorter front to back). I bought the size of my head measurement and it fits perfectly. It is also very lightweight and have great ventilation. My head circumference is 55cm and I bought size S/M 51-58cm (printed on helmet).

For anyone who has trouble looking for helmets (pressure at temples, difficulty sliding helmet on as it get stuck on the sides of your head, etc.) this is the helmet for you. I was skeptical since I have to get a 2XL-3XL Bern helmet for snowboarding. The M/L Round Fit is an absolutely perfect fit for me. You don't get the fore/aft shifting that makes the helmet lopsided while riding or wearing it. USER TIP: Be sure to loosen the adjustment dial first before trying it on, otherwise you'll think it's too small for your head per usual. Tiighten it afterwards and it fits like a baseball cap.

We are a round head family. I tried many helmets in store and ordered a few online. Finally, this one in size S/M worked, nicely. I gave it to my daughter, who has slightly bigger head than me. I kept the regular starvos wave cell helmet in size small for myself. It is a little long in the anterior-posterior direction, but it is wide enough for my head and no pressure point.

Although I hope you never need it for this use, I got him by a car while wearing this helmet and flipped over and hit my head. The helmet saved me and really kept it's shape and structure. Bontrager customer for life.

We are a round-head household and we like safety. This helmet fits so well that we got one per person. Safety wise, this helmet scores high on the Virginia Tech helmet ratings. Fit wise, this helmet is one of the few round-fit bike helmets on the US market for now. Earlier we bought multiple helmets online and none fit - they were all too tight at the temples and gaping around the forehead. Then we discovered the round vs oval ("classic") fit helmet after reading the "Bicycle Helmets for Rounder Heads" on helmet dot org. The other option is the Specialized Mode bike helmet in round fit. For snow sports, Burton/Anon offers round fit. We're really happy that REI stocks this helmet in the rare "round" fit and even has it available in store for try on. Thanks REI!

I'm from Japan and until now i always had to wait to go back home to get "Asian Fit" (round fit) helmets. the circumference of my head was about 22.5 inches, i say about because i used a cheap measuring tape with no mirror to guide me and it was close enough i figured. the size S/M fit perfectly! now, i don't really care for this wavecel stuff, whether it works better or not, doesn't matter to me. i rather not have it so i can scratch my head. plus im pretty sure it's less ventilating and aerodynamic. but for $100 at REI im not going to complain.

I've been searching for helmets that are designed for rounder heads—some call it the "asian fit". They're difficult to come by, but this is definitely it! But sadly, a tad bit too round for me. Turns out I was able to find a more suitable fit with a different helmet.

I've been unable to find any normal helmet that fits me, even XL ones. Finally got recommended to look for a round fit helmet, and this one is perfect! Comfortable and great fit for me. I am Asian btw, the "Asian fit" is real

So far so good. I don't really like the design or the color - I like neon colors! I have an odd shaped head - wider than longer - thus the normal oval shaped helmet would move everytime I hit a bump on the road and i'd have to stop and re-tighten the adjustment. I just wish the round fit comes with a "BOA" tightening instead of the rather flimsy tightening dial.

This is an excellent helmet for those who truly have round heads. I’m Asian, and have great experiences with Oakley’s Asian fit glasses. The same now applies to this helmet, I’ll be purchasing Bontrager’s round fit helmets going forward, insofar as they keep making them. The helmet is relatively light, it’s definitely comfortable, and the straps don’t interfere with my ears or sunglasses. Now Bontrager, please start making premium priced round fit helmets, that’s the only thing missing.
