Carnac Croix road and gravel helmet review

Can you really get a decent road and gravel helmet for under £25? Carnac’s Croix is a lot better than you’d expect on a budget

Our Verdict

Decent shape with reasonable ventilation, fit and comfort at a super low price, but side buckles need TLC


  • Good looking shape
  • Hardshell for protection
  • Lightweight
  • Lots of vents
  • Washable pads
  • Reflective straps
  • Loads of colors


  • Only two sizes
  • Side buckles are delicate
  • Limited through venting

Planet-X sells a range of helmets from £20 upwards so the Croix is a comparative luxury item at £25. Despite most other brand's entry-level helmets costing considerably more it manages to compare well with lids twice the price and above, too.

Styling of the Croix is certainly on point with 24 mid-size vents and a raised ‘spoiler’ built into the rear. The EPS foam liner is protected right to the edge with a hardshell ‘skin’ and it exceeds the EN1078 safety standard for bike helmets.

In use, there’s a decent amount of radiation ventilation from the numerous holes and slim pads don’t get in the way. There are no internal channels that limit airflow at higher speeds but that’s the case with most helmets under £50. While there are only two sizes and the cradle isn’t height-adjustable it’s a decent shape that fitted most testers without too much wobble. You get an occipital pad to stop the dial section digging in and there’s a pad on the chin strap too, which is removable if you want to look more ‘Pro’. The straps also have reflective bits which are a nice detail at any price. The adjustable sliders are a bit flimsy and we’ve already snapped the closing cam off one but it still works, it just doesn’t lock. There are 13 different matt or gloss colors available to make it easy to accessorize. Molding is surprisingly clean too with only the rear strap anchor protruding slightly more than you’d see on a top-quality lid. 

If you fancy treating yourself to an upgrade, Planet X has the Carnac Podium SL comes in three sizes, with internal channels and anti-bacterial pads for just £29.99.

Detailing is basic up close and the side buckles are a bit fragile but Carnac’s Croix is light, comfortable, reasonably well ventilated and looks decent in a wide range of colors for an absolute bargain price.
