Nice looking helmet at a great price!

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

I'm trying out my first road bike ever this year and it's been an adventure to say the least. Picking out the right gear for the first time is a little difficult, but I have to say I love this helmet. Everything about it is great. The look is nice and it's pretty lightweight. It fits great and having the adjustable loc in the back makes it feel secure. It's a great price and I feel safe in it!

It's a helmet

  • Familiarity: I've put it through the wringer

A helmet is a helmet in my opinion (excluding aero helmets), as long as it fits and is comfortable i am happy. This has been going strong for years and does exactly what it is supposed to. I do not understand spending more on a helmet, this does everything you could possibly need.

Saved my head!

  • Familiarity: I've put it through the wringer

I am a new road biker and purchased this helmet based off the reviews of other users. I recently wiped out on my bike at approximately 10mph and was thrown about 10 feet from my bike (watch out for those railroad tracks)! I remember my head bouncing off the cement and I have to thank this helmet for saving me from a more serious injury. I walked away with some bruising and a mild concussion. My helmet is scratched and the foam cracked all the way through so it definitely did it's job! I'll be purchasing a replacement Savant ASAP. Always wear your helmet!!!

Saved my head!

Saves Your Noggin

  • Familiarity: I've put it through the wringer

I purchased this helmet over a year ago and have worn it on every ride. I have found that the helmet fits my head very well (it's somewhat small as I'm a petite girl) and doesn't give me a headache or pressure spots on long rides. It also doesn't feel like it's weighing my head down, which keeps my neck from hurting. I recently got into a nasty crash, and this helmet came through for me. I was thrown to the ground (asphalt) with considerable force and my head bounced off the pavement. I nailed the right side of my head-that resulted in a cracked helmet, but a fully intact skull. For the price I don't think you'll find a better fitting and performing helmet. I've worn several different Specialized helmets prior to this and this helmet wins hands down. The highlighter yellow is an added hi-vis perk, if you ask me. :) Also, Giro does have a crash replacement program. But, thanks to the awesome Backcountry deals, I was able to get it cheaper here than that of the crash replacement discount. Incredible!

What really matters.....

  • Familiarity: I've put it through the wringer

I've had this helmet for the last two years. It always fit really well with a bare head or a winter beanie - particularly with Giro's Roc Loc system, never felt overly heavy when compared to other helmets at much higher prices and I personally liked the looks of it. With all of that being said, I can tell you that this helmet performed extremely well during a crash this past weekend. My bike came out from under me on a sharp turn and some loose gravel and my head bounced - yes, bounced - off the pavement. After I dusted myself off and took stock, my head was fine and was able to finish off the ride. Looking over the helmet it had a few dents from the impact but by all accounts I have a fully functioning brain. Now you could go spend $300 on a POC Octal with its self-proclaimed safety benefits, but this $90 Savant has my lifelong support after saving my noggin this past weekend.

great product, great price

  • Familiarity: I've put it through the wringer

I purchased this helmet at the same time that my wife purchased a 200 dollar helmet. i cant get her to stop wearing mine. the quality is fantastic, and it fits sooo snug with their adjustable sizing system, i can just about wear it with out using the straps. its light enough not to notice (i dont know why people insist on buying things any lighter than this, at that point you might as well complain that your hair is to heavy)
great product at a great price

Will Oakley M frames fit in the vents?...

Will Oakley M frames fit in the vents? (size medium)

The Oakley's you have should not have any issues fitting along with the Giro Savant helmet.

Great helmet

  • Familiarity: I've put it through the wringer

This is a really nice helmet if you want something that wont break the bank. Working in a bike shop I've tried a few helmets and this still is one of my favourites and have had 2 over the last 2 years. Its a super comfy helmet and offers really good ventilation as well. Giro never disappoint.

The black foam strips in the helmet can be removed. Giro also includes additional blue foam strips for even more precise fitting. Replacement black strips can be purchased for about five bucks.

The Savant is an extremely light helmet and offers good protection. The Matte Black finish matches my bike:) The fitting system enables you to put the helmet on your head, turn the dial to your size, and you're set. I also like the ability to take the foam cushions out of the helmet and clean them.

Perfect affordable helmet

After wrecking and cracking my Ionos, I wanted to find a cheaper replacement. The Savant is a perfect alternative. The fit is very similar, and the vents are nearly the same. Oakley Radars fit in the vents the same too.

Great alternative for 1/3rd the price.

Awesome helmet

Fits perfectly to my shape. Great helmet for the price. Vents on helmet are good and kept me cool for the century ride at Sea Otter Classic.

Good Helmet

Very good value helmet that works well and is quite light. Keeps you cool in the summer as well.
