Ratio MIPS Helmet

Proving you don't need to fork over excessive loot for a comfortable fit and peace of mind on the mountain, the Giro Ratio MIPS Helmet offers a superb fit, MIPS technology, and adjustable ventilation within a cleanly sculpted, no-nonsense design. The Ratio's hardshell construction employs a rugged outer shell that's attached to an EPS foam liner for impact absorption in the event of a crash.

To ensure a truly custom fit, the In Form system rapidly adjusts the helmet with the quick spin of its rear dial. Where this fit system really shines, though, is with its ability to fine-tune the vertical orientation of the helmet on your head so you won't have to deal with an embarrassing gap between the helmet and goggles. The Ratio's MIPS liner separates itself from other helmets in this price range, giving this helmet the ability to disperse angled impacts on the mountain. Standing for Multi-Directional Impact Protection System, MIPS technology consists of elastomeric attachment along the liner, which creates a slip plane in the event of an angled impact. This slip plane allows the helmet's impact foam to rotate independently around your head, subsequently reducing rotational forces before they're transmitted through the helmet.

Fits My Big Melon + MIPS = Happy

Familiarity:
I've used it several times

I read online that Giro helmets tend to fit heads that are oval-ish front to back. Meaning, longer front to back, than side to side. I measured, bought the XL and was very pleased with the fit when it came. A MIPS helmet in this price range is tough to beat. I use it with sunglasses, so can not comment on the goggle strap quality.

Goggle Clip snapped - 2nd use

Familiarity:
I've used it once or twice and have initial impressions

Giro has designed its goggle holder clip with a rigid (but not terribly thick/strong) plastic. One side snapped in its 2nd use from the normal force of moving goggles on/off. The other side snapped the next ski day. Shame as otherwise a nice helmet. Clip needs to be made of a flexible material. Backcountry was great re replacing,

need to improve material for goggle clip

Familiarity:
I've used it once or twice and have initial impressions

Bought this helmet. It functions very well except the issue with goggle clip. During the first use, the goggle clip broke into two pieces as it's made of hard plastic. This type of plastic is very easy to break, especially under low temperature (25F during that ski trip). Compared with the Smith and Bolle helmets we owned. The clips on other brands are made of soft resin or silicon with button. Giro needs to redesign the material!
