Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Product Reviews
Rated 5 out of 5 by from Most comfortable MTB helmet! Absolutely love this helmet. Tried hard to go with either the POC Tectal or Kortal prior to buying this one and I'm so glad I did! It fits like a glove and I totally forget I'm wearing it while riding. It's by far not as bulky as the POC helmets and it also feels at least subjectively lighter. Love the color schemes as well and cannot praise the fit of this helmet enough. Sizing is spot on and the magnetic buckle is also a plus.

Rated 5 out of 5 by from Great fit. Quite pricey, but I agree with everything outdoor gear lab has to say about it! The rotating top makes a lot of sense once you feel it. Ventilation is great!

Rated 5 out of 5 by from Only Giro for me! This is my 5th Giro helmet and they do not disappoint. Each newer version is better than the last, which isn't always the case. This helmet is comfortable, light and good looking and the magnetic chin claps is far and away the easiest I've ever used.

Rated 4 out of 5 by from Great but pricey This is possibly the most comfortable helmet I’ve ever worn. It’s ventilation is excellent. Safety features seem to be top of the line. Not sure if it’s worth the price though.

HOW to MEASURE
HEAD CIRCUMFERENCE: Wrap a flexible measuring tape or string around your head, keeping it level from front to back. Note the measurement and reference the Size Guides above.

NOTE: Giro recommends you make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you've got the right size, you can adjust the fit.
