WRSi are great. White water Reasearch and Safety Institute. It is a safety institute that is associated with John Hopkins Research Centre.
Hey Bex, don't believe everything you read on the interweb. These guys are about as valid an institute as the club, eh, wait that sounds wrong. Anyway, they're very controversial, try looking them up on Boatertalk. That said everyone says the helmets are good, but the back story is not as simple as their website says.
Why are you on the internet so much - is Uganda really rubbish or something? You're missing all the water here.
And another thing, in general...
Lots of folks buy helmets that initially give good coverage and then wear skullcaps under them, resulting in poorer coverage on the forehead. This seems to be particularly true of the trendy freestyle helmets. Watch out for that.
