My whole family uses this helmet as our primary lid and we've always been happy with the weight and placementnumber of air vents. It is often hot riding here in Texas and we enjoy a helmet that doesn't smother. We just replaced my son's because he went over the bars. The helmet worked as advertised and took the impact preventing a concussion, at the very least.
I fell on my road bike when I slid on a muddy patch of road on a rainy day. My Giro helmet protected me as my head bounced along the asphalt. The side of the helmet looks like it was worked over by a power sander. The MIP System performed as advertised when my head twisted and rubbed on my left side. As I write this review I am ordering another Giro MIPS helmet to replace the one that saved my brain. This is the most important piece of safety equipment you will ever buy.
Let's face it, there are a lot of good helmets out there and all of them must pass the same DOT standards. The MIP System is a fairly new feature, but I consider it a must, since almost all cycling accidents involve lateral impacts. The Giro Synthe with MIPS also has a one knob adjuster that makes it easy to accommodate caps, sweatbands etc. For the price it can't be beat and it looks great.
Got out the on a ride for the 1st time with the new Savant. The secured fit was outstanding and being a little chilly, I wasnt able to provide feedback on the venting, well find out in warmer weather. The look and feel of this helmet for a large to XL size head is the best Ive had. The only exception or reason for the four rating is my hair gets caught in the MIPS inside tabs.
Spokane's review is right in line with mine A very good lower-cost (but not cheap) option for a quality helmet. It's a lower-profile design, nice and light on the head, with a true fit. The dial in the back is good quality. The only negative is the rough chin strap. Other models I've worn (e.g. Rudy Project), have a much softer material in their chin strap that add comfort. The strap on the Giro is a bit rough. Not going to ruin your ride, just a minor negative.
I have tried on several helmets and the Giro Savant MIPS was the most comfortable without spending an excessive amount of money. The chin strap adjustment knob is also of good quality. The MIPS version has a layer of plastic between your head and the pads adhering to the styrofoam material, providing that extra cushion. As stated in other reviews, you have an excessive amount of chin strap material after making the fit adjustment. I ended up cutting off the excess and used a flame to prevent fraying. Of course, at this point I pretty much bought the helmet, making the possibility of return doubtful. This provided my motivation for not cutting off too much. The appearance was not sacrificed, however. Another complaint is that the narrow cushions inside the helmet were not secured properly. I had to add some additional velcro strips to prevent them from flopping around. This really should have been done at the factory. After making these modifications, I have a nice looking helmet that is very comfortable and affordable.
