Why We Like The Eclipse Spherical Helmet

Whether we're racing on pavement or breaking away from the pack on gravel, the Eclipse Spherical Helmet has everything we need to keep us comfortable and protected. A total of 14 wind tunnel vents pull air through the helmet for incredible cooling power, and MIPS brain protection guards against rotational forces upon impact. The Roc Loc 5 Air system enhances stability and fit, and plush Ionic+ padding helps absorb sweat and moisture.

Great fit; when others failed miserably

I've used it several times
Size Bought:

With some other top line helmets I cannot get a fit that keeps the helmet stable when I am down in the drops. This helmet is perfect in terms of stability and comfort. Additionally, independent reviewers rate it very highly for safety and aerodynamics. Plus its blue color is a perfect match for my blue Trek bike!

Excellent helmet

I've put it through the wringer
Size Bought:
5' 9"

Best helmet I've used in over 40 years of cycling! It's aerodynamic, producing minimal wind noise while cruising at 22mph. The fit is excellent and required minimal set up. I like that it can be adjusted mid ride with a simple rotation of a thumb wheel at the back of the helmet. The helmet straps don't buffet in cross winds/head winds which minimizes noise as well. All in all it is super comfortable in a broad range of temperature ranges. I live in north east Florida and have used it in temperature ranges of 95+ with high humidity and temperatures down to the high 20s without any discomfort.
