Comparison review: Seven High-End Helmets

The big differences between the top models, as our testers discovered, are in fit, finish and features the three "Fs" of helmets. We graded these premium lids on their quality of finish and attention to detail. Ventilation systems were checked in all weather from hot and hotter, to wet and cold. Can you operate the vents with gloves on? Does the chin strap flog you half to death because there's no snap to secure the end? When your helmet starts smelling like a bear's den, can you remove the pads and wash them? The answers to these and other burning questions are included in our premium helmet comparison test, but the most important question is "How do you make sure you buy a helmet that really fits properly?"
