    An aero helmet with holes in it!

    When Louis Garneau set about designing an aero helmet, they didn’t forget the most important thing –air. As in, the air has to move over your head to keep you cool so that you can actually continue to ride hard enough to take advantage of aerodynamics. The Course Helmet is the result. It’s no slouch in the wind tunnel, but much more importantly, it’s a very comfortable helmet to wear, even on long rides, and even in the middle of summer.

    Great all-a-round road helment

    • Familiarity: I've put it through the wringer

    Its light. easy to get adjusted. fits my head comfortably. I like the fact its semi aero too. It even comes with a small light on the back.

    Does everything at average

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I've had this helmet for about 18 months now and my opinion of it has slowly declined. Though it's subjective, it's a comfortable helmet for me. I looked at the Kask Mojito (didn't like the leather chin strap) and Giro Synthe and ultimately just wanted something a little different than the Giro, since I already had an Atmos. The good thing is this is a low profile helmet - it doesn't look goofy and it doesn't look big; however, for me, that seems to impede on ventilation and sweat management.
    I don't think this is a well ventilated helmet in that I never feel airflow through or over my head and sweat just tends to drip directly onto my face - a bit frustrating in Texas summer. Agree with some of the comments below, that the retention system feels cheap and flimsy, but I've had no issues with it in 18 months of use. I've had no crashes in it, but one knock of the retention system is that it seems to have a lot more wiggle room and play in the fit unlike some other helmets with a sturdier retention system - almost like it lacks a little structure.

    While helmets are very subjective, the LG Course didn't really work for me. It's not a bad helmet by any means, but it's not a good/great helmet either. It's really just an average helmet.


    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Medium

    I love the look of this helmet. I have had it for a little over a year now and it fits like a glove. It is a really comfortable, light, and ventilated helmet. It keeps the head cool and looks good. I highly recommend it.

    I like it but not not enough to keep it

    • Familiarity: I returned this product before using it

    I bought this helmet from Backcountry and returned it. Thank you Backcountry for making returns easy! I would have kept it if I didn’t already have two helmets but since this was a somewhat frivolous purchase I sent it back. It’s fairly low profile, round, light, and well vented. The rear blinky is an awesome bonus feature but the retention system seemed cheap and not very comfortable. Overall I didn’t like the helmet enough to replace my Giro Atmos and since it’s expensive I had to really like it to keep it. I ended up getting a Kask Mojito instead which I love.

    The original aero road helmet

    • Familiarity: I've used it several times

    This lid is well ventilated, light, compact and aero. It works well for road racing and tri's. For triathlon and TT, traditional aero helmets are only aero with your head up. Once you put your head down they are like air brakes. This helmet allows you to relax your head a bit and still be aero. Excellent product.

    Good Quality. Good aero qualities.

    • Fit: True to size

    First Ride: Just got back from a long windy hard ride and this helmet seems much more aero than my Specialized S-works or Giro. It was kind of cold out so I can't honestly say how well it breaths/cools. The fit is good, but honestly, most helmets seem to fit my melon pretty well. Maybe a little less comfortable than my Atmos. Several folks have mentioned the Course's poor quality, frankly, I don't agree. Maybe these people aren't familiar with "race" helmets or got a few bad-apples. But as far as I can tell, this helmet's quality is on par with any helmet I've ever owned.

    Good aero and ventilation, poor clips

    • Familiarity: I've put it through the wringer

    PRO -

    - good aerodynamics, seems just as good or better compared to the Giro Air Attack (I've ridden both extensively)
    - good cooling, a little (but not a lot) better than the air attack
    - significantly better looking than the air attack, in my opinion


    - catches bees in the helmet over 10x more frequently than the air attack, get stung in the head about once every two or three rides (>150km) during the summer
    - strap clip (I think they are called strap dividers) broke spontaneously, I substituted a heavy rubber band meant for mounting a bike computer that seems to work well, actually better than the fancy clip. I hope it's not meant to be functional in the event of a crash (though the clips are clearly brittle and flimsy so I'm guessing they are meant to break off in the event of an impact).
    - much less comfortable than the air attack, presses against forehead due to minimal padding vs the air attack that has a terrific suspension system that holds the shell away from the head. My head circumference is 58.7cm and I wear a Medium in both helmets.
    - because it holds the foam pressed so close to the skin on the forehead, it leaves tan marks that are exactly shaped like the front openings of the helmet, these marks make you look a bit like a klingon when off the bike and are basically permanent throughout the summer. The correct solution of course is to spend as much time on the bike wearing the helmet as possible so that nobody will notice.

    This review is based on 10000km+ on both this helmet and the Air Attack. In spite of the negatives with this helmet, I continue to use both helmets quite extensively. I choose the air attack in cold/rain/snow/sleet and the Garneau Course in high heat and sun particularly above 30C (my air attack is black and my course is white which also affects this choice).

    Good helmet for racing

    • Familiarity: I've used it several times

    (Updated) I've used this helmet for over a year. As is obvious from the picture, the Course looks rather like a compact regular road helmet but with an unusual vent scheme. Where most aero helmets present a smooth surface to the wind to limit drag, the Course is designed to simply let air straight through. So ventilation is what makes the helmet aero. Exactly how many watts you'll save at race speed I cannot say. Assuming it works, and it seems to, this is a clever solution to helmet aerodynamics. Looking at the helmet straight-on, the structural parts of the helmet present a minimal profile to the wind, so air flows right through almost as if nothing is there.

    No question that this is an expensive helmet, and its target audience is those who race who are looking for marginal gains. If you're a commuter who simply wants to get somewhere fast, this kind of helmet won't increase your speed enough to justify the cost. In bike racing, even a savings of 5 watts means faster recovery, fewer matches burned, and more speed in a breakaway or pursuit situation. For them, this helmet can be worth its cost. But this is also a first-generation aero road helmet and there may be better options if performance is the key variable in a purchasing decision.

    Summary of the advantages: First, the helmet is aero, at least in the optimum position(s)--headwind and head tilted just so. Second, the helmet looks good. Third, the adjustment system works efficiently. Fourth, I love the LED light that comes with the helmet and attaches to the back harness so drivers can see you.

    The downsides to this helmet, as I see them. First, I don't think the helmet is well designed to handle crosswind situations and may be as bad or worse than a non-aero helmet. This is speculative, but it is hard to believe that the structural ridges handle wind well from the side (which can happen simply from turning your head, too, as well as from a crosswind). Second, the internal padding is not exceptional and will absorb sweat quickly...eventually to trickle into your eyes. Third, the padding has a tendency to leave indentations on my forehead. As another reviewer mentioned, it's kind of Klingon-like.

    I can recommend this helmet, but only if the opportunity arises to get it at a discount (or for aesthetic reasons). At full cost, there are more recent designs that offer better performance and look pretty good too.

    comfy, well vented, & understated looks.

    • Familiarity: I've put it through the wringer

    This helmet fits great and stays put. The frontal vents do an excellent job of pulling in plenty of airflow to keep things cool. Also, in an era of loud, obnoxious looking helmets, I really like the simple and clean design, especially with the white color option. It's tail has a more rounded profile which ought to help in the aero department when you've got your head down, suffering like a dog (and the tail of the helmet up) in the winds. Though it's noted to be recommend for road usage, it's equally well suited for XC mountain bike application.

    holds your glasses well, too.

    • Familiarity: I've put it through the wringer

    Fits my head, straps feel minimalistic, retention dial is easy to find, and my sunglasses go easily into the vents as long as I flip them upside down (which is the best way to do it, anyway, so the lenses don't hang down into your field of vision).

    Great aero helmet

    • Familiarity: I've put it through the wringer

    I have used this helmet in 90 degree days and it cools as well as a Giro Aeron but is much quieter. If less wind noise means smoother air flow, it must be doing the job aerodynamically but I have no way to measure this directly. It fits great and the light on the back is reassuring in the evening.

    Comfy helmet that's aero ?

    • Familiarity: I've put it through the wringer

    I really like this helmet. Apparently it is quite aero for a road helmet (I have no way of testing that myself), but it vents well and is more than sufficiently adjustable. I'm not sure what else I would expect from a helmet. :)

    Unanswered Question

    Is this the one that was recalled? I heard that the Louis Garneau Course Helmets with model number LG1261 printed on the inside of the helmet. “Garneau,” “Course” and “LG” are printed on both sides are the recalled bicycle helmets.
