More open area helps when you are moving, but at a stop any helmet traps heat.
Yes, but the airflow that cools you in summer will also chill your scalp in winter.
The foam is still continuous around the head; vents are openings in the shell, not gaps in protection.
A thicker liner takes up space, so the helmet may feel tighter until the liner packs down.
Vents move air over the scalp to carry heat and sweat away. More open area means more airflow at speed, but also more exposure to sun and rain. On a commuter or skate helmet, vents are usually paired with a removable liner that can be washed or swapped.
On road and mountain shapes, deep internal channels pull air from the front and push it out the back. That works best when you are moving. At a stop, a heavily vented helmet feels like any other helmet.
Most ventilated helmets use an in-mold shell where the outer polycarbonate is bonded to the foam. The vent openings are molded into both layers, so the edges stay clean and the foam is not exposed.
Liner material matters for comfort. Some models ship with two removable liners so you can run one while the other dries. Others use fixed padding that is thinner and more open.
Mountain and skate shapes often have fewer but larger vents, with deeper coverage at the back of the head. Road shapes run more vents in a row from front to rear. Commuter models split the difference with a mix of top and rear vents.
