I dare say there was some purpose to it aerodynamics 
Just had a look through a lot of the pics online, and I see only Cav had his helmet "vacuum wrapped" or whatever it was, Wiggins and Froome seemed to have a union jack hardcase cover and from what I see of Millar and Thomas they had no covering at all, don't know about the others though.
In fact, just twigged what it was all about, they must have banked on Cav winning, so planned on partying ASP afterwards and did not want there hair ruining to go out
A few years ago Briko brought out a helmet called the "Twinner"
Basically a helmet with a second one on top
The concept that the outer helmet would be more aerodynamic without vents, and the gap between the two layers would cause sufficient airflow to cool through the vents on the inner layer. This relies on air being pulled through vents in the gap - the Venturi effect
Looking at the helmet on the TV it certainly looks high enough to be of this type of design, with vents beneath the outer clear layer but unless the back is visible then t is difficult to be certain

marginal gains + sponsorship, innit.
He has to wear whatever type of helmet it is because of sponsorship deals, and that type doesn't have an aero cover available so they shrink wrapped it instead

Covering up holes in his helmet is not technically UCI legal, can't believe he was the only one that did it though.
I don't think taping up holes on a helmet would constitute a change to the design or form as described in the UCI rules. As for the helmet Mark Cavendish was wearing on Sunday, I would suggest the clear cover was designed for use with his helmet and wasn't just some cling film from the hotel kitchen.

These might be a good winter option, I'm thinking warmer and dryer. Does anyone know where you can get them?
Other solid helmets look like WW2 rejects.

If I am right than he hasn't as with the twiner these are not vents, but channels, the vents are at the front for intake and at the back to produce the Venturi effect

Maybe it had given out rain and he had just had a perm?

Often the case, but traditionally, if a rider doesnt want to wear the sponsor's item, they dont always HAVE to. Typically they get around it by branding another brands product up as the sponsors. A few years ago, Cadel Evans rode a bike the same as the PX stealth in the TdF TT one year, branded as a Ridley. Many riders including Lance Armstrong have done similar things with sadles, San Marco saddles branded up with the sponsors name.
