I decided to do triathlon properly after my first sprint attempt. I used a pretty crappy mountain bike helmet in that event, and it only just passed inspection (didn't even realise at the time that they did helmet inspections).
So I went down to my local triathlon shop, SBR in Windsor, and had a long look at the helmets. I wanted something light, strong, sleek and black (in my black phase, other colours are available). I wasn't quite prepared for the price I would have to pay to get all these features in one package, but it quickly became obvious that the Giro Atmos was the helmet for me.
Here is a very positive review of the Atmos.
I've been very happy with the Atmos. I hardly know I'm wearing it except for the chin strap which I might have done a bit on the tight side. As the review says, it is very light, it has a lot of ventilation (has been used in 35-40C in the south of France), and I'm assured it is strong though, hope never to put that to the test. I've also worn it all winter in rain/sleet and snow - it's probably pshchological, but it also seems to keep my head warm.

Do yourself a favour, and get a helmet like this one, not some cheap alternative from Halfords.
