POC Octal helmet



Distinctive looks backed up with impressive fit, ventilation and lightness, and a colour that will ensure you stand out on the road; not cheap though

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

With its distinctive looks, the Octal is Swedish-based POC's first go at a road cycling helmet, after giving us the truly unique Tempor time trial helmet a couple of years ago. It looks unlike any other on the market, but looks aside this is a well ventilated, comfortable fitting and light helmet, and in this colour you're sure to stand out on the road.

You're either going to like this helmet's appearance or you're not; I'm not going to try and convince you otherwise. What I would say is that you should withhold your opinion until you've actually seen the helmet with your own eyes rather than just the photo up top. As a piece of design, I think it works. The more time I spend with it, and the more I see Garmin-Sharp riders wearing and winning in it, the more it's growing on me.

Once you're wearing the Octal you can't see what it looks like anyway, and the fit is where the Octal scores a few bonus points over many other helmets. It's rare to slip a helmet on and it to feel just good and comfortable straight from the box, with no adjustment necessary. It's supremely good. The closest comparison is the Specialized Prevail, another very comfortable helmet.

It takes some getting used to though, mainly because the helmet is quite wide and comes down lower at the sides. That's to provide more protection for the skull in the event of an impact with the ground, but it does feel unusual for the first couple of rides compared to regular helmets. You soon get used to it though and after a ride or three it feels normal. Just a new normal.

The reason for the Octal's looks is because POC have designed 20 huge vents, deciding that fewer, but larger, vents is the best way forward for best ventilation. It's certainly a theory that is backed up by performance; compared to a Specialized Prevail and Catlike Whisper the Octal is significantly better ventilated. It's light too, just 204g on the scales which you notice immediately. However it's still some 15g heavier than the £50 cheaper Prevail.

As for the colour, POC's mandate with the helmet has been to choose colours that it reckons boosts visibility on the road. There's no denying that this is a colour that will raise your visibility to other road users, especially at this time of year when it's often gloomy or very cloudy. There's a more conservative white colour which is probably the pick of the bunch, or you can emulate the Garmin-Sharp team with a blue option. It would be nice to see a wider palette in the future, a black version would go down nicely with those cyclists who don't want a high-vis helmet.

The retention system is unobtrusive, and adjusted via a small dial at the back. It's easily adjusted on the move, but you don't need much pressure on it; the Octal stays in place well, with minimal movement. The straps are easily adjusted so they sit just below the ears.

A minor niggle is the lack of compatibility with various brans of glasses, including my Oakley Radarlocks and Uvex Sportstyles. Because of the thickness and lower coverage of the helmet sides, there just isn't the space for the arms of the glasses to fit in. It's a blemish on an otherwise really well thought out helmet.

Speaking of eyewear, the Octal has a unique 'eye garage' in the two front vents, basically two small high-friction pads that cling to the arms of your sunnies, so you can pop them in the helmet when you don't need them on your face. However, I had mixed results with different glasses, some working just fine and others not so well. It's a nice idea but one that doesn't work as well as hoped. Compatibility with eyewear is a small niggle, but it's one I'd like to see addressed.

Showing safety is a key concern to POC, the Octal comes with an ICE tag. This is a barcode that you stick to the back of the helmet, and once registered with all your important contact information can be scanned by any medic with the appropriate app. It's a nice idea, but will medics have the relevant app on their smartphone to scan the helmet if they scrape you off the road?

Going a step further, the Octal is compatible with the ICEdot Crash Sensor. It's a small sensor that clips to the back of the helmet and relays location data via Bluetooth to an app on your smartphone. Have a crash and it'll start a timer, if you don't stop the timer before it reaches zero, the app sends an message to the emergency services.

You also get a nice cycling cap with reflective graphics for night riding, and a soft fabric bag to store the helmet in. It's available in three sizes, small, medium and large, three colours and comes with EN 1078, CPSC 12.03 and AS/NZS2063-2008 certification.

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

POC says:

The award winning Octal helmet is engineered to be the next step in road bike helmet safety. It offers optimal ventilation, comfort and weighs less than 200 grams (size M, CE-version).

Octal provides more coverage and additional protection of the temples and back of the head. To further improve safety, the EPS liner is strategically thicker in most exposed areas and is covered by the outer PC shell.

The unique and fully wrapping unibody shell construction functions as a monocoque and enhances the safety properties and construction integrity of the helmet while maintaining a low weight.

POC has approached ventilation in an innovative way and instead of using many small vents, Octal has fewer, but larger, ventilation slots. This design provides a larger open surface area at the front, and in combination with the specifically designed interior, allows more air to flow through the helmet.

The ultralight size adjustment system ensures a comfortable and secure fit and the internal Coolbest padding helps reduce the temperature in the interface between the helmet and your head.
