What the helmet! Saved my head in high speed crash.

What the helmet! Saved my head in high speed crash.
UPDATE 7/22/2020 - Today, I flipped over my bars on the road portion of a gravel ride. At about 16 mph, I locked up the front wheel, and was catapulted head-first over the bars. I landed on the crown of my head then rolled onto my back and the back of my head skidded against the pavement. The helmet took the brunt of the impact. I was able to walk away from this accident. I went right to urgent care and am happy to report that although I am bruised on my back, my head and neck are 100% FINE. I have full range of motion and no concussion. Although this helmet lacks MIPS, it absolutely saved me from grievous injury or death today. Pictures attached. Thank you so much, teamobsidian!----------------------------------------Great lid with no weaknesses. Compared to the Louis Garneau that it replaced (after a serious impact), this is about 10% smaller all around. I'm a short guy and a big helmet looks ridiculous on me. No mushroom-head here, I am very happy to report.The matte surface feels velvety smooth. The seams between outer shell and inner foam is seamless. You definitely FEEL like you got your money's worth. After about 3 rides, I can say the ventilation is excellent. Pads compress very little over a ride and seem to handle head expansion (due to heat) without any tightening. This was a big problem with my old helmet.The chin strap is very comfortable, doubly so due to the velcro pad that goes over the straps. The straps have quick adjusters on them, so you'll get your fit down in about 15 minutes and you can fine tune during a ride. I;ve actually been able to adjust with one hand without getting off the bike -- they are THAT easy to use.I wish the helmet had more reflective material on it ... but I understand that is not the trend these days, so I get the reason for this. However, if a few optional reflective stickers that matched the style of the helmet were included in the box, it would be perfect. I imagine the white helmet would probably be more reflective than matte black, but white wasn't available when I purchased this.

For the price this helmet ranks a 5. It may not be the best looking but it is a well ventilated and I like the way it is sized. My previous helmet was a small and the band had to opened up all the way. The medium was way too big but I later found that I had to have a second helmet to accommodate a cap in winter. These use different sizing -the medium is small enough to not look over sized and big enough to accommodate a knit cap. My guess is that Medium will accommodate size 6¾ - 7¼. I wear a 7 and the adjuster is set about in the middle. I also like that it is better vented than most, is light and the internal structure seems a good thing. Also the pads a nice. The user guide says the can be cleaned. The fabric feels much sturdier than the cheap pads that fall apart so easily on my previous helmet. The mat finish, I decided, is a nice touch.

This is a decent helmet at a good price. It's very comfortable, lightweight, and the air vents work well.

The helmet size is adjustable, but if your head size is on the larger size of the range listed, I suggest you get the next larger size. I got the M/L and my head size is 59 CM. It fits, but there isn't a lot a adjustability left.

5.0 out of 5 stars The Bike Helmet I've Been Looking For
Reviewed in the United States on November 13, 2023

The Team Obsidian 'Airflow' helmet has a colored 'shell' that looks like it's actually fused with the styrofoam base, meaning it's all one piece. For me, this uniform design is cleaner & is simply the way it should be.

There are two U.S. CPSC (Consumer Product Safety Commission) compliance labels underneath.

The side straps that come down your ears are adjusted using a simple, but clever, flip-lock buckle. To adjust the strap on either side, you 'unlock' the buckle by flipping a piece outward to loosen its grip on the strap, then pushing back the same piece inward to lock the strap in place. To me, this is much faster than the belt-like adjustment on other brands' helmets.

The chin strap has a click lock with a contrasting red color & a microfiber-like padded chin guard that can be removed if you wish. The chin strap's length uses a traditional belt buckle type adjustment, but is otherwise easy to do. A substantially wide (about 1/4 inch) elastic band keeps the excess length tucked-in neatly.

You can fine-tune the fit by turning an adjustment dial in the rear. The dial's edges have a red non-slip silicone border to help your fingers get a grip when turning. There's a vertical (height) adjustment feature mentioned on the Amazon product page. Unfortunately, the included documentation in the box does not describe how to do it. The plastic parts of the adjustment system are identical in quality to the other more expensive helmets I have.

There are 22 large air vents. The foam pads inside don't appear to be any different in quality from others I've seen, though they are obviously narrow since they must fit in the slim space between the vents. I measured my head at 56 cm., so I ordered a size S/M, which goes up to 58 cm. per the size chart. It was a true to size out of the box & fit snugly as a helmet should. I did turn the rear adjustment dial both ways just to see how the fit changes, but the size range felt right.

Overall, this helmet is comparable to others that cost far more. The S/M size was $20 at the time of this review. In my opinion, that's a great deal.

5.0 out of 5 stars Great Bike Helmet!!!
Reviewed in the United Kingdom on July 5, 2016

The helmet arrived very fast, in a great package and in perfect condition.
It is extremely light, which makes you wonder at first, but I've already tested it on the long run and I'm happy to say that it remained comfortable and light even after I used it for a few hours.
The shape is also very aerodynamic and the inside assures a good grip and a comfortable positioning.
The safety straps are also easy to adjust and to secure and they are very comfortable as well. I find this very important as I used to have a helmet that was scratching my skin with its straps and it was a great pain to wear it.
i'm also happy I chose the white color because it doesn't heat up while wearing it on sunny days.
I definitely recommend this product. It's worth every cent!!!

5.0 out of 5 stars Comfortable and Easy to Adjust.
Reviewed in the United Kingdom on November 16, 2016

I bought this helmet as my then current helmet had become uncomfortable to wear and seemed to have a design flaw that finally I couldn't put up with any longer. I wanted a helmet that was both comfortable and afforded protection. TeamObsidian claim this will be the most comfortable helmet you will ever wear. I can't say how accurate that is other than it is the most comfortable I have worn to date. Adjustment was a doddle and the knob to tension the interior straps is large enough to grip with cycling gloves on, yet not so big as to be unwound by the collar on your jacket (which was the case with my old helmet.
As far as protection is concerned it does seem well constructed and fits well which goes a long way, however until you need it to work you will not know how much protection it affords.
