The key word here is Ventilation.

Your standard of ventilation may not meet mine because you get what you pay for when it comes to helmets. Having said that, I would not buy a $110.00 dollar helmet if it did not come in white because that color is cooler in the summer.

A helmet with 15 vents is going to cost money any way you look at it. I think the cheaper helmets are perfect for the winter.
