Lazer Z1 KinetiCore.
KinetiCore crumple zones molded into EPS replace traditional MIPS for rotational protection without added weight or fit complexity.
The Verdict.
Gavler Meta-Score
“KinetiCore delivers rotational protection without a separate MIPS liner, but the Z1's real story is weight: at a measured ~226g it's one of the lightest helmets you can buy with rotational protection, and it carries a 5-star Virginia Tech rating. If you already prefer a light, airy climbing helmet, this is among the best — just don't buy it expecting a bargain or RollSys to be simpler than a rear dial.”
The Gavler Verdict
Precision Engineering
KinetiCore Technology
Crumple-zone EPS blocks moulded into the shell break and deform in a crash to manage rotational forces — no separate MIPS liner required.
Featherweight Build
Claimed 220g (size S), measured ~226g — about 27g lighter than the next-lightest helmet Cyclingnews had tested.
Advanced RollSys Retention
Top-mounted dial tightens the entire cradle at once; reliable and hot-spot-free, though more involved than a standard rear dial.
Technical Specifications
The Scoreboard
Praised as one of the lightest helmets available with rotational protection, backed by a 5-star Virginia Tech rating and excellent airflow. Marked down where reviewers find the RollSys retention more complicated than a simple rear dial — and it's a premium-priced helmet, not a value pick.

Global Critique
“The Lazer Z1 Kineticore is impressively light. If that's important to you, the rest of the Z1 is capable enough to let weight be a determining factor.”
“Kineticore accomplishes the same thing as MIPS but there's no extra layer.”
“The lightest helmet I've used.”
