What can you get for a quarter these days?

The Giro Quarter MIPS Helmet is one of the lowest-profile helmets Giro has ever made, and it’s also the lightest they've made with an ABS shell. The essentials are here – an EPS liner for impact management, a tough outer shell, riveted webbing anchors and plush, sweat absorbent pads that are easy to swap for dialing in the fit. Another standout feature – the polyurethane coating helps to protect the EPS liner from daily wear and tear. Available in a bunch of great colors and three Super Fit™ sizes. Quarter MIPS models are available with the Multi-Directional Impact Protection System. MIPS increases the "slip plane" of the helmet, redirecting energy and providing more protection in certain impacts.


  • MIPS-equipped low profile helmet with an ultra-lightweight ABS shell.
  • External polyurethane coating protects the EPS liner from daily wear and tear.
  • 8 vents allow for maximum breathability.
  • Available in 3 sizes: Small (51 - 55cm), Medium (55 - 59cm), Large (59 - 61.5cm).

Tiny head

I really loved the helmet. The color was really nice but I was so disappointed that I had to send it back due to the fact that I have a really small head. I have a hard time finding hats and helmets to fit. If I had a big head I definitely would have kept it.

Yup, it's a helmet

I got this helmet for my son who rides his bike all around his college campus, and to all his off-campus excursions. I bought it for 2 reasons 1) MIPS. We all hope we never actually need to use the helmet for what it's designed for. But if you crash, you want the best. 2) Not too many air vents, cuz it's cold in Chicago!

Certainly more helmet than a road bike one, feels safer.

Well, I purchased it for something different than what it was designed for I think bicycle touring. I just wanted a different look and the high visibility of the orange is amazing. The helmet is heavier than you might expect when you read the description lightweight, but then it isn't a road helmet. I'm not sure what the helmet will be like if it gets humid, but I think mid warm temps it might work well.
