Here's how to get the best protection for your head

Bike helmets  

A bike helmet must fit snugly to protect you. “Try on the size you think you need, and then try a size smaller,” says Rich Handel, Consumer Reports' assistant test project leader. (Warning: Don’t be tempted to buy a larger size for your child, thinking she will grow into it!)

If you’re buying a bike helmet online, check the return policy to make sure you can exchange it.

Another important shopping tip: Wear a ponytail or a hat when shopping if you ride that way; those things can alter the fit. Then use our tips to make sure your helmet fits you properly.

Check the fit

·         The helmet must be level on your head. It's not a bonnet!

·         The front edge should be no more than an inch or so above your eyebrows.

·         The strap should fit closely under your chin. You shouldn't be able to see daylight between the strap and your chin.

·         Straps should meet just below your jaw and in front of your ears, forming a V under your earlobes.

How do you know whether the helmet fits?

Push the helmet side to side, then front to back, and give it a twist. (The skin at your temples should wrinkle.) The helmet should move only a little bit.

If it’s too loose and your helmet has an adjuster knob, tighten it, or if your helmet came with extra pads, use the thicker ones. If it’s too tight, turn the knob to loosen it or use the thinner pads.

Will it stay put while you’re riding?

With the heel of your hand, push up on the front edge of the helmet. If it exposes your forehead, shorten the front straps. Then grab the back and try to push the helmet forward off your head. If it covers your eyes, shorten the back straps.

You’ll know the chin strap is tight enough when you open your jaw halfway and feel the helmet press down on your head.
