Happy, i mean the first Bell ones, all white with a red stripe or two, hardly any vents at all.

And aura, when I said 75 bucks, heck there are $45 helmets that are pretty darn good, with good ventilation.
Really, all I was getting at was how is great that reasonably priced helmets are light enough and comfortable enough with good ventilation to wear on hot day climbs.
Seeing the cute young lady with that helmet just made me remember how uncomfortable the early ones were.
Along of course with the added bonus that wearing a helmet is complete second nature to me now, and it doesn't bug me even on hot climbs.
I tend to keep them for ages before replacing them, usually when the inside stuff is completely worn away.

Interesting connection to how i grew up skiing without a helmet but it took only a few runs with one on to become completely comfortable with it, and wouldn't ski without one now (keeping warmer is a nice bonus too)
