The Tonic KinetiCore is aimed at the recreational road rider who wants low weight without giving up rotational protection. Instead of a separate MIPS liner, Lazer's KinetiCore uses EPS foam blocks that crumple on impact to absorb direct and rotational energy, which Lazer says avoids added plastics and reduces the foam needed. Lazer lists 240 grams for a medium CE helmet, the lightest figure published on this list, along with 18 vents and a cooling efficiency of 97.2% compared with no helmet. The Advanced TurnSys dial adjusts with vertical travel, eyewear docks in dedicated slots, and a rear Direct Mount takes the Universal Lazer LED. Four sizes run from 52 to 64 cm, and a winter kit fits S, M and L. Lazer offers a Crash Replacement Program and a 30-day money back guarantee. The tradeoffs: Lazer sells it through dealers without listing a US price, and its page does not name a certification.
