The LeMieux Verv Competition Helmet is a show helmet built on a corrugated ABS twin shell with a reinforced polycarbonate rim, a 360° wrap fit you tighten with a rear control wheel, and click-on top panels and magnetic peaks you can swap. The LeMieux Vexa Skull Helmet shares the shell, the wheel fit and the Coandă airflow system, with a grip surface that holds a hat silk in place for cross-country.
LeMieux lists both helmets as tested to EN 1384:2023 and ASTM F1163-23, and the Vexa listing adds BSI and SEI impact testing. If your saddle pads, boots and bonnets are already LeMieux, the Verv is the helmet that matches them. The helmets below are the ones riders reach for when they want the same job done by a model they've worn for years.
Stay with LeMieux if
you want swappable top panels and peaks, or your kit is already LeMieux.
Look at the alternatives if
you want years of rider fit reports, Mips, or a lower tier.

One K is the closest match to the Verv's swap-the-look idea. The One K Mips CCS Helmet takes One K's CCS color system of interchangeable panels, front shields and vent rails, with a Mips liner, an anti-microbial layer and a padded harness, as One K lists it. The ASTM-certified One K Defender Helmet comes in regular and Long Oval shells.
Riders tell us One K is the helmet they forget they're wearing: comfortable from the first ride, cool in summer, and easy to fit without fussing with straps. Look elsewhere if you want a skull cap; One K's lineup here is peaked show and schooling helmets.
Stay with LeMieux if
you want click-on top panels and magnetic peaks.
Switch to One K if
you want the custom look with Mips, or a Long Oval shell.

I had not hear of the One K brand and tried on the more recognized name brands first. This was by far the most comfortable--and it has interchangeable inserts to help with sizing (although the L fit perfectly). I like the no fussing around with many adjustments to straps (because it doesn't have a lot of straps and buckles).
I love my One K MIPS helmet, which has a wide brim option. Personally, I wouldn't consider any helmet without the MIPS feature. I previously owned a CO MIPS and *hated* it. Heavy, hot, and ill-fitting.

For a skull cap, the Trauma Void Lynx Eventing Skull is the direct alternative to the Vexa: a Mips liner, laced neck, mesh-backed vents and a washable lining, at about 560g by Trauma Void's own figure. For the ring, the Trauma Void EQ3 NEOZ Helmet pairs Mips with a Coolmax interior, a magnetic snap and an adjustment wheel, and Trauma Void lists it as SEI ASTM F1163-23 certified.
Riders tell us Trauma Void fit them when other shells didn't, especially riders moving over from Charles Owen and riders who sit between sizes. Trauma Void shells suit a rounder head; if yours is long and oval, start with One K Long Oval or the Equinavia below.
Stay with LeMieux if
you want the Vexa's grip surface for a hat silk.
Switch to Trauma Void if
you want Mips in a skull cap or a show helmet.
Trauma Void helmets
Shop all ›The Trauma Void helmets fit me SOOO much better than the Charles Owens. It’s been a huge uptick in my quality of life. I can’t even describe. I was a devoted CO owner but had issues along the way. Headaches, helmets would only fit well for 7 months or so and then they’d stretch.
I tried on several OneK helmets, but not the MIPS one, and I seem to be between sizes so none of them fit. For reference, my head is 57.5 cm. I got the Trauma Void in a 58, because that's what they had, and it fit better than any other helmet I tried on

The Equinavia Crown Mips Riding Helmet is the helmet riders with a large, very oval head keep naming. Equinavia lists a Mips safety system, a wide flexible brim, a chrome-coated frame with front, top and rear vents, a memory-foam lining you can wash, and dial-adjustable fit, certified to ASTM F1163-23/SEI and CE EN 1384:2023.
Riders tell us the Crown Mips was the one that fit after they'd tried Mips and Charles Owen models that didn't, and that it sits a tier below most of this list. Crystal and glossy versions give it the dressed-up look the Verv's panels are built for.
Stay with LeMieux if
the Verv's 360° wrap fit sits right on your head.
Switch to Equinavia if
your head is large and very oval, or you want Mips at a lower tier.

I have the Equinavia Crown MIPS helmet for my very large oval head and I love it. There's a limited range of brands where I live, I drove around a bunch of tack stores, tried on a few MIPS and CO models and none were right.
Equinavia Crown Mips Riding Helmet
I've just bought the Equinavia crown MIPS helmet and love it for my large and very oval head. Very reasonably priced too

Shires Karben brings the leather-look, suede and crystal finishes of a competition helmet down to the $$ tier. The Shires Karben Amity SMRT Riding Helmet pairs a matte frame with a matching center panel and a dial fit, and the Shires Karben Sonic Alessa Wide Brim Crystal Finish Helmet adds a wide brim and crystal trim. Shires lists the Amity as certified to ASTM F1163-23 and EN 1384.
Riders tell us the Karben dial fit ends the pressure points other helmets gave them, and that the details look like a far more expensive helmet. Look elsewhere if you want Mips: the Karben helmets here use a standard liner.
Stay with LeMieux if
you want the Verv's shell and fit system.
Switch to Shires Karben if
you want a dressed-up finish at a lower tier, or pressure points bother you.
Shires Karben helmets
Shop all ›I recently bought a Shires Karben WP helmet with a dial. It's a revelation - perfect fit and no more headaches from pressure points.
Shires Karben Sonic Marzia Wide Peak Helmet
This is a fantastic option for a budget helmet that's still stylish but won't break the bank! The details make it look more expensive, and I love the wide brim. I have an oval head shape and this model fits me perfectly. You really can't beat it for the price!

Pick the helmet that fits your head first, then the look. These four steps get you there.
Riders tell us comfort and fit decided it: helmets they forget they're wearing, that suit their head shape, and that keep them cool.
One K Defender Chrome Stripe Helmet
Finally! A helmet that fits well AND looks good on. I've been riding for over 40 years and this is the prefect schooling helmet. Well done OneK!
Trauma Void Pardus Smooth Helmet
I have an oval head and like my Back on Track Pardus very much. It has a dial fit that I did not think I would like, but I do.
Shires Karben Matteo Riding Helmet
The ventilation is no joke. My head stayed cool even while the rest of me was melting into the desert.
I've always ridden in COs, since I traded in my old hunt cap for an actual helmet. I needed a new helmet this summer to replace my CO MyPS but didn't like any of the new COs that I tried (AYR8, Halo, and Kylo). I also tried a few Trauma Voids and didn't like them either. I wound up with a OneK CCS that I love more than any helmet I've had in recent memory.

Questions riders ask
LeMieux lists the Verv Competition Helmet and the Vexa Skull Helmet as tested to EN 1384:2023 and ASTM F1163-23, and the Vexa listing also names BSI and SEI impact testing. Check the label inside the helmet against the rules for your discipline.
The One K Mips CCS Helmet is the closest match. One K's CCS color system swaps panels, front shields and vent rails the way the Verv swaps click-on top panels, and the One K Defender comes in regular and Long Oval shells.
The Trauma Void Lynx Eventing Skull is the closest alternative to the LeMieux Vexa Skull. Trauma Void lists a Mips liner, a laced neck, mesh-backed vents and a washable lining, at about 560g.
Riders with a large, very oval head tell us the Equinavia Crown Mips Riding Helmet fits when other shells don't. The One K Defender in its Long Oval shell is the next one to try.
