i'm wanting a new helmet. i currently am using a bontrager helmet with wavecel. i my third season with it and this year i seem to be sweating more and more. age maybe? more aggressive riding? regardless, i feel the wavey stuff impedes air flow and i'm wanting some more air flow. have seen another helmet at LBS but had something called koroyd. sales guy says it has better air flow but it seems way too similar. anyone with experience using this i'd like to hear about it.

i have a chrome dome and wear a bandana underneath to help manage the sweat. it helps but i still find i need to wring it out at least 2 times on 30mi rides. in the end i am looking for max air flow with protection of course.

I can't address your question as I have no experience with koroyd, but I do have a helmet with wavecel. As for sweat, consider using a skull cap rather than bandana. Likely your bandana is made of cotton and cotton doesn't wick moisture that well. And also the bandana will have many folds in it and may be more insulating. Skull caps are typically made of synthetics and are very thin. The moisture wicks away and dries very fast. While more airflow is a good thing either way, you might find a skull cap works better than a bandana.

My issue with Wavecel is you can't slip sunglasses into the helmet.

There are more than a halfdozen other major helmet brands. Just buy a different brand and model, one with good ventilation reviews.

didn't know about this. will be getting one or something like this to try out. can't wait to see how this works out. thanks.

A cycling cap that is not cotton will help wonders. Plenty of excellent options, Walz and Pace both make fine ones that I have worn and continue to wear. My favorite helmet which has great ventilation is the Lazer Z1.

In a similar spirit to a bandana, there are more purpose built items you might want to try such as the Halo band with the sweat gutter

I can't compare to Wavecel, but I have found that Koroyd reduces air flow a lot. That said how bad it is depends on how/where it is used in the helmet. I switched from one brand/model Koroyd helmet to another and it made a big difference. That was due to more/better open channels of airflow. Read reviews and look at the helmets.

Oh man, remembering that heady week when Trek promised to “change cycling forever” with their upcoming announcement, and then the letdown when it was just helmet filling

It was hilarious in all the wrong ways.

I like the product but the gutter has detached on my last two. Maybe they have a lifespan of a year.

If max airflow is the goal, Wavecel and Koroyd both feel like compromises.

I switched from a WaveCel Bontrager to a Kask Valegro with Koroyd panels last season, and the difference in airflow was night and day. The Koroyd channels let way more hot air escape, so I’m not constantly wringing out my sweatband anymore. Protection still feels solid—Koroyd crumples predictably on impact like any good liner.

Why not just get a more conventional helmet that has good air flow? There are plenty of them at all price levels that have excellent airflow and five stars from the Virginia Institute that test the helmets to see how well they protect.

I shied away from Wavecell because it just looked like it'd be hot. I have no idea what Koroyd is, but it sounds about the same as Wavecell. I'm sure they protect well, but when conventional helmets protect just as well, why not just get what looks like it will flow air through it?

I've never felt the wavecel cooled any less that other helmets I had used in the past. My only real grief with them is that I had to remove the helmet if I had an itch on my scalp that I can't resolve by shuffling the helmet around. A solid positive is that bees\wasp were no longer an issue going into the cooling channels. I am actually on the hunt for a new helmet as my current one is a bit old and I like to replace them every 3 or 4 years just for peace of mind. I know there is probably not anything wrong with it, but it's my head. Prices for helmets have gone insane since I last looked.

Koroyd seems to be a different type of wavecel-ish type protection that crumples on impact.

Ok, so helmet fit for me is odd as my head shape does not work with some helmet brands, so did you find the Kask fit odd compared to the Bontrager? I've not had issues with Bontrager and Bell helmets. I tried on a Smith and it felt ok, but brands like Giro just do not work for me. I hate online shopping for some things like shoes and helmets unless I know exactly how things are going to fit, but no one local carries Kask. How did you like the fit?

Agree, in Southern Arizona this is the answer for the summer months, rinsed after every ride with your helmet it works well.

Agree, but they glue back on with good multipurpose glue and then last many many years.

Made the mistake of using superglue on one, and it created a nasty crusty abrasive patch where it leaked through. What do you use?

Yes it is different. And I can only imagine since I've never used either, but maybe it will flow a little more air than wavecell.

Still, I'd think conventional helmet designs that are aimed toward ventilation as their selling point will have more air flow than either. Maybe not, as I can only speculate. Neither type have proved themselves to be any more safer than conventional helmets or conventional helmets with Mips technology.

When looking for a helment when wavecell was newer tech, The Bontrager helmet did fit my skull the best. However I passed on it as it seemed it'd be too hot for the weather I ride in here. And there was no evidence that wavecell was any better than Mips. And still none today AFAIK.

Well they don't make it any more, it was recommended to me and I did not pay much attention but got it at a fabric store. Mine is slightly coming loose so I am gonna get some zgorilla Super Glue and try that.
The original is a thermoplastic glue so I think one might be able to put it back on with a small amount of heat but not with the glue I put in the joint.

I saw a video where they used a sewing machine to put them back together permanently. Looks like a winner.

Did you hand wash or put in the washing machine? I saw a review of these things and the guy said that he used it a lot, not just cycling and threw in the washer with other stuff, and that it ended up pulling the diverter off the material. He said he would hand wash the next one. I order one the other day before I saw this thread and should be here tomorrow, so my plan is to just hand wash it.
