Team Obsidian Airflow Adult Bike Helmet - Lightweight Helmets for Adults with Reinforcing Skeleton - Unisex Bicycle Helmets for Women and Men - Comfortable and Breathable Cycling Mountain Bike Helmet

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.

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.

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.

On 07/09/22, I received my seventh e bike helmet. This procedure can be a daunting effort. For all those individuals with a large round head there are very few companies producing helmets and size charts that will actually fit our heads.1. VicGoal 2.KingBike 3.Vcan 4. Moon 5. Vega 6. Vcan None fit!!!!! 7. Team Obsidian was the only one that fit. !!! But it's not DOT rated or MIPPS rated. From the reviews I have read everyone has survived their accidents or crashes . The helmet is lightweight, comfortable, easy to adjust but the Black Helmet is not illuminating, a light , reflector or some florescent stripes could have been added . The Helmet feels like it's made out of styrafoam . Therefore: I rate it at 4 stars because it fits. 07/31/22, I added these photos and customized the helmet with chrome adhesive strips to enhance the visibility of vehicleur traffic awareness in the daytime and nightime. I also mounted a light on top ofthe helmet that has a white light in the front and a red constant on or flashing in the rear for night biking.Ted CabanDunnellon, FL

I like the small reflector sticker in the back and the bright colour, being that I ride mostly at night. Plenty comfortable and a good fit. A thin winter hat fits nicely underneath.

I purchased the Team Obsidian Airflow helmet in December of 2018. Used the helmet for about 3/5 days per week. Immediately impressed with how lightweight it was and the overall quality for the price. The molding being worked into the frame of the helmet is a nice touch. I usually will run a product through its paces before thinking about leaving a review. After 6 months of heavy use the tension system on the helmet failed. That said the helmet has held up great overall. What really impressed me beyond my expectations was the customer service provided by Team Obsidian. I reached out to them about the tension system, and it is a very uncommon failure point in these helmets but these things happen. Really prompt and helpful customer service, reassured me I would be taken care of, sent me out a brand new helmet right away. I usually don't expect much from smaller companies on Amazon, figured after the 6 months of use I would need to just buy a new helmet. Really amazing to see a company stand behind their products and also have your back! While the helmet has some great features and quality for its price point, you can rest easy knowing Team Obsidian will have your back if any issues arise.

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!!!

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.

Well the helmet arrived and I thought the box was empty as it was so light. The fit was excellent and helped by the adjustable small wheel at the back. Very light on the head with comfortable chin straps. Well worth the extra money. Thank you Team Obsidian

it's a very light helmet but feels comfortable when wearing it.You can adjust it easily to make it tighter or looser. Hopefully I don't have to use it in case of an accident, but I'm sure it'll protect me. I'm really happy with the product.

This is the lightest helmet I've had. It's well vented, comfortable fit, easily adjustable, and my wife says it looks good! Seems to be sturdy, haven't tested it with any head on pavement yet and hopefully I won't have to.
