That's a helmet, lights, turn signals, a brake light, ERT and crash detection in one, not just foam and a strap.

PATENTED TECHNOLOGY

ERT: Energy Reduction Technology

Most helmets are built for the rare, high-speed crash and do surprisingly little for the everyday knocks. Woolf does both. ERT is a patented layer of soft, advanced polymer pads that manage rotational as well as linear impact energy. Ordinary EPS foam stays rigid until a certain force is reached, then engages. ERT responds instantly, including at the lower-speed impacts linked to many concussions, which is exactly where standard foam does least. In independent lab testing it managed linear impact 30% better than EPS foam alone, and cut rotational force, widely believed to play a major role in brain injury, by 26%.

Softer is smarter.

Built for both kinds of impact. The twisting (rotational) energy behind most brain injury and the straight-on (linear) blow. Standard EPS is designed for the blow alone.
And for the speeds that matter. Engages at the low-speed impacts that cause most concussions, where stiff EPS barely reacts.
Independently tested. Outperforms EPS on both counts in the lab, by 30% and 26%.

ACTIVE VS. PASSIVE

Why Woolf is the smarter choice for urban riders

Standard Helmet (Passive)

  • Protects on impact, then does nothing else.
  • No way to signal a turn without taking a hand off the bars.
  • Only as visible as the reflectors you stick on.
  • If you come off, no one knows.
  • Bulky the moment you step off the bike.

Woolf Helmet (Active)

  • ERT that manages rotational and linear force, tuned for the low-speed impacts behind most concussions.
  • Hands-free turn signals trigger with a tilt of your head.
  • A brake light that fires automatically the instant you slow.
  • Crash detection that shares your location with your emergency contacts.
  • Folds to 35% of its size, so it comes anywhere with you.
