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

Excellent fit, adjustability and value for the money. This helmet compares favorably to much more expensive helmets. The helmet is well made, light weight, flows air well, and looks good.update: I crashed my bike on black ice and slammed my head to the pavement before I could do anything to prevent it. The impact felt like someone had smacked an open hand real hard on my helmeted head, but no worse. The impact was immediately dissipated and absorbed by the helmet. I didn't even get a headache but the helmet suffered a one inch crack and a five inch crack spread radially from the temple impact site, a total loss but the helmet saved me from a certain fractured skull and concussion, or worse. Thank you Team Obsidian for a well made helmet. I immediately ordered a new replacement helmet and it arrived today. Five well earned stars for this helmet.

I never used a bike helmet before, but everyone kept nagging me that I should. If I was going to get one, I wanted a quality product, not some cheap plastic thing. So I chose this one even though it was more expensive than a lot of other ones.I am very happy with my purchase of this helmet. It's lightweight but robust and very well constructed of good quality materials. Easy to adjust, and to put it on and take it off. It fits quite well and comfortably. I've worn it for hours at a time and could almost forget I I had it on. It holds my adjustments so I've never had to readjust the fitting since when I first got it. I like the sun visor attachment and keep that on all the time. In fact, I specifically wanted a helmet with a visor, which is one of the reasons why I chose this one.Having never owned a bike helmet before, I have no previous experience to compare it with, but I am quite satisfied with the quality and comfort and safety level provided by this helmet.

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.

I have a huge head, and finding bicycle helmets big enough that don't cost a fortune is difficult. I was glad to find this helmet and, while I had to put it on the biggest setting, it does indeed fit. It's not as comfortable as my really expensive one, but it does have a little extra padding in the front that is removable, so that is nice. The helmet also comes with a visor that you can attach on the outside of the helmet. The instructions don't tell you what it is or how to attach it, but I did figure it out fairly easily. (It clips on via the four plugs on the visor; there are four receptor holes on the front.)I'm still fiddling with the straps a bit... even though I was able to get a snug fit on the helmet, the front part of the strap assembly (the part in front of my ears) is too loose, and I'm trying to figure out how to appropriately adjust the front straps so that all four are snug. It almost seems like it doesn't matter, but I think it would be better if there wasn't any give. I also wish the little wrap/pad thing that goes over the strap was attached somehow. I don't think that's going to last very long, and it's too bad because that is a nice feature.It's still too cold (for me) to go riding, but when I do, I have a back up and/or an extra one for a house guest.
