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 Helmet I Have Ever Worn I purchased this helmet after a crash cracked my other one (and saved my life). This is without question the most comfortable helmet I have ever put on my head. It is as though I am not wearing a helmet at all. The look has far less mushroom effect as some others I have tried. Sunglasses fit nice and secure on the helmet as well. I am very happy with my purchase and would gladly buy the Helios again.

Rated 5 out of 5 by from Love it! For most things I wear while being active, a true testament of performance is how comfortable I am while using the item. This helmet truly hits the mark because, to me, I don’t even notice it while I’m riding. Pretty remarkable.

Rated 5 out of 5 by from Light and comfy Rode over 50miles on a warm day. Almost did not feel the helmet due to comfort and lightness. Very good ventilation and an excellent fit for my head.
Date published: 2021-04-21
Rated 5 out of 5 by from Great Fit - MIPS! I did quite a bit of shopping. I initially purchased a lazer G1, but the helmets see to be rounder than my head. This help fit well as it is longer front to back. I purchased a medium in the Helios where I could only fit in a large in the lazer. Very satisfied.

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.
