The S-ONE Lifer Helmet is designed to fit low on the head like a traditional helmet, but it has a break through design combining the added safety and protection of a CPSC certified helmet with the comfort and feel of a soft foam helmet. The Lifer has an old school look with the traditional circular air vents and a high-impact EPS foam inner mold for maximum protection. The liners can easily be removed or replaced.

What's up with the S-One Lifer helmet?

The S-One Lifer Helmet is our top favourite. It is dual certified, which means you can wear it to be protected for one single large impact and multiple smaller impacts. That is exactly what you need for derby, as both types of impact occur regulargly, also to you. Safety is key, and you definitly want to protect your head to the best of your ability. S-One test their helmets to other brands' options all the time and without a doubt, the S-One Lifer Helmet comes out on top.

On a practical level, the liners can easily be taken out and replaced. After all the sweating, you can just replace the liners and the helmet will feel as comfortable and nice as a new helmet. Check out the options below.

The S-One Lifer will feel a bit tight upon purchase, but the liner has to settle a bit while you wear it. This model sits deep on your head and is somewhat oval shaped. 



  • Dual Certified
  • High impact / Multi-impact EPS Fusion Foam
  • Deep fit design - fits nice and low on your head
