Good find.

The reported results aren't particularly surprising, given that they were looking at 800-gm cricket helmets. That's quite a weight to be carrying around on your head. Most decent bicycle helmets are around 300 grams.

The different requirements of the two sports more or less mandate the weight difference---or to put it another way, the practical upper limit for helmet weight is lower for sport and racing cyclists than for cricket players and football players.

But with those findings, here's hoping that attempts will be made to reduce the weight of cricket helmets while maintaining protection at as close to the present level as possible.
