Rotational Force and low-level Impact Protection.

PATENTED TECHNOLOGY

ERT: Energy Reduction Technology

Most helmets are built for Olympic, rare crashes and do little for the smaller knocks. Woolf goes further. ERT is a patented layer of soft, advanced polymer pads that manage both rotational and linear impact energy. Ordinary EPS foam stays rigid and kicks in above a certain force, but ERT responds instantly, even at the low-speed impacts that cause most concussions. Studies suggest around 80% of crashes fall into this lower range, exactly where standard protection does the least. Softer, it turns out, is smarter.

Manages both rotational and linear impact energy, not just one.
Engineered to work at low impact levels, where the majority of concussions and brain injuries are thought to occur.
Proven in independent labs: 26% better at managing rotational impact and 30% better at linear impacts than EPS foam alone.

ACTIVE VS. PASSIVE

Why Woolf is the smarter choice for urban riders

Standard Helmet (Passive)

  • Protects on impact , and then does nothing else .
  • No way to signal a turn without taking a hand of the bars.
  • If you come off alone, no one is alerted
  • Bulky to carry the moment  you step off your bike or scooter.
  • Only as visible as the reflectors you stick on.

Woolf Helmet (Active)

  • ERT energy management tuned for the low-speed impacts, behind most concussions.
  • Hands-free turn signals you trigger with a tilt of your head.
  • An automatic brake light that fires the instant you slow.
  • Crash detection that shares your location with your emergency contacts.
  • Folds to 35% of its size so it actually comes with you.
