Cool, comfortable lightweight helmet with great airflow

The Stradivarius has been part of MET's line up for years but the latest tweaks mean new pads, a lighter ratchet system and Homothetic Embedded Skeleton or HES for short. It all adds up to a comfortable, lightweight race helmet for a decent price.

Helmet fit is just as personal as saddle comfort but I found the MET absolutely spot on in terms of shape and long term comfort. The majority of this is down to the gel pads. Made from polyurethane Morpho-gel they don't flatten against the head like the usual foam pads in the majority of helmets, even when tightened.

They feel cool against the skin and remain so even when you're really going for it plus they keep the helmet slightly away from the head to allow airflow. They also grip a sweaty forehead without absorbing any of it and they're anti-bacterial and hypo-allergenic so they don't need washing. Lots of benefits without any drawbacks.

Add those cooling effects to the massive number of vents on the MET and you've got one refreshing helmet when you're in the hills on a warm summer day, or in your hallway on the turbo giving it some with an inadequate fan replicating the wind.

The Safe-T Advanced retention system is easy to adjust and is said to "deliver pressure in a homogenous manner" thanks to a broad surface area. Whatever you make all of that I certainly didn't feel any pressure points or discomfort so I guess it's doing its job.

The webbing weave has been fettled to keep the strength while losing weight and helps bring the medium size test sample down to 257g which is a pretty good figure for a helmet of this price and it certainly feels light when you are wearing it.

So what is HES? The Stradivarius is constructed from two similar skeletal shells that are fused together in a way that transfers the shock around the helmet rather than it just focusing on the point of impact. Whether it works or not is difficult to see without the test data though and that is rarely available.

There is an Australian version available (not to us in the UK) which has passed the more stringent AS/NZ 2063's Load Distribution standard which tests exactly this but it weighs a claimed 25g more so obviously needing beefing up a bit more than the EN 1078 version we get in the UK. I'd be happy to sacrifice a little bit of weight for that peace of mind.

Overall the MET Stradivarius is a very good top flight race helmet that for me at least is one of the most comfortable I've ever worn, the gel pads making a huge difference to comfort especially when things are hot and sweaty.

The price is acceptable against its competitors and while it might not be any more safe or stronger than the cheapest helmets out there all wearability is much more important in the long run.

The only downside I can see is that it's a shame they don't just sell one model that passes all test criteria across the world.


Cool, comfortable lightweight helmet with great airflow. The Oz version seems better though.

Stu knocked out his first road.cc review back in 2009 and since then he's chucked the best part of seventy test bikes around the West Country, a couple of them quite literally! With three alloy and two steel bikes in his fleet he's definitely a metal man (that'll be the engineering background) but is slowly warming to that modern carbon fibre stuff along with fat tyres & disc brakes.
It's not all nostalgia though, after spending the last few years in product design Stu keeps banging on about how 3D printing is going to be the next big thing and he's a sucker for a beautiful paint job too.

I recently purchased a Met Stradivarius as an upgrade to a Catlike and can only say the retention system was designed by someone with little knowledge of the head shape. After one 50 mile ride I had to return the helmet for a refund due to the retention points digging into the lower head. Let me state, this will not effect everyone but if you happen to shave your head or keep your hair pretty damn short avoid this helmet at all costs.

The two lowest retention points are hard plastic and have nowhere to go but dig inwards, as your gaze adjusts to differing horizon gradients these points dig and scratch at the skin leaving lesions even on a short ride. Having now done a little research it appears this is common problem with the Met retention system and not just on the Stradivarius.
