I'd like to explain the helmet hat concept away by saying that, as the creators of the NYC condom, "fuseproject" figured they'd continue their success by sticking with the theme of things you unfurl over your head. However, I think the more likely explanation is that somebody who knows nothing about cycling thought they could make the helmet "cool." This is typical non-cycling hubris, and the result (a helmet hat) is predictably idiotic. A non-cyclist who thinks he or she can somehow solve the "problem" of helmets not being cool enough is like the person who knows nothing about plumbing, insists he can fix your faucet for you, and winds up flooding your bathroom. The truth is that helmets are the one aspect of cyling in which you actually should just copy the racers. A GI-style skater helmet or a modular helmet/hat nightmare looks no better than a typical racing-style helmet, which you can buy for like $30 or $40, which will be lightweight and well-ventilated, and which will accommodate a wool hat underneath (or, yes, a non-decorative helmet cover above if you prefer) when it gets cold:

It's also typical of the non-cyclist to focus on the helmet as a symbol of cycling safety. Indeed, the helmet has become a symbol of safe cycling just as the condom has become a symbol of safe sex. However, there's a big difference between the two. If you use a condom properly it will be highly effective, but if you use a helmet properly it won't make a difference if you're still doing everything else wrong. Riding without a helmet will not make you crash, but riding with a bunch of stuff dangling off your handlebars might. If the City of New York and "fuseproject" really cared, they'd have designed a really "cool" and convenient basket instead of a helmet:

Instead, they just bull****ified the helmet, which is about as meaningful as their safe sex campaign would have been if they'd used brightly-colored *****s instead of condoms. Really, they might as well have just promoted retro-chic 1980s hairstyles that also have potentially head-protecting qualities, such as the classic high top fade:
