Manta - The most aerodynamic road helmet

MET developed the MET Manta specifically with aerodynamic performance in mind. It’s quite simply one of the most competitive sprinters’ helmets in the game, saving you 10 watts at 50km/h.

With a NACA crown duct and optimally positioned vents throughout, the MET Manta will keep heads cool, without increasing drag.

The Manta is the lightest helmet of its type, tipping the scales at just 200g.

Safe-T advanced fit system

Safe-T Advanced, MET’s micrometrical fit system, provides the best weight and comfort ratio.

The contact points have a larger cradle surface increasing comfort and are also designed to keep weight low and allow perspiration at the back of the head.

The polyurethane soft padding improves the fitting affording a comfy head touch.

DualGel front pad - Double-density blend, polyurethane gel padding

Benifits of DualGel

  • Hypoallergenic and antibacterial, maintains a neutral odor.
  • Longer lifetime use compared to traditional pads, and keeps original thickness.
  • Helps cool the head.

Helps to keep your head cooler when pushing the limits. The gel pad does not absorb perspiration and offers a much longer life span than traditional foam pads.

Durable, comfortable and built to last, DualGel padding is mountable on any MET helmet.

Excellent fit and lightweight The only slight issue is the strap feels a bit cheap. My old helmet was a Kask Vertigo which had an excellent leather strap. Thats why i didn't give it 5 stars

Met manta white

Easy to wear and fit, it gives you a high level of safety


nice fitting than met rivale, my head is wider hence manta fits me well. rivale is a lil narrower than manta.

Nice helmet

After trying more than 7 helmets with different brands, I found Met Helmet suits my head most. As compared with other helmets, I tend to find helmet with less holes but with aerodynamic shape. I like the design and the colour (black / yellow / blue).
