FEND Super Helmet with Ultra-Bright Lights - Adult Mens and Womens Bike Helmet - Collapsible by 50% of Original Size - Safety Certified for Bicycle Road Bike Scooter Cycling Commuter Helmet

Protip: Order one size up as the sides of these seem to run narrow, as they're optimized for portability. The company has a helmet guarantee and was happy to exchange the helmets for me w/ comped shipping fees. Amazon doesn't have a category to return or exchange for fitment issues, but you can contact the vendor directly and avoid tarnishing their return metrics, ha.The product and company seems to be new, as most if not all of the current reviews have a Vine attribution. I pulled the trigger despite it being an expensive $130 helmet, and have no regrets. This helmet looks, feels, and even sounds great! It has a nice snap+click feel and sound when expanding so you know it's tightly locked when expanded. Definitely a crowd pleaser! Exterior of helmet is hard plastic with two inserts for lights, inside has typical styrofoam protection.The light attachment (front and rear) operation are simple to use, and easy to detach. You can hold it down for 1+ seconds to turn it on. Once on you can single tap the light to switch flash modes, such as: constant, strobe, fade. Must take helmet off in order to see that mode it's on, but I'm confident to just hold the button while riding to know that it's on when going through dark tunnels with cars. It also fades in and out to when plugged in, to indicate it is charging, which is nice. Note that you must use a 5v type-c or the supplied type-a to type-c connector to charge the lights. They're secure and snug, and detachable by wiggling and pulling, or pushing outwards from the inside of the helmet.My only two nits with this helmet is the initial issue with size, if you have a wide head, I'm worried large may not be big enough. The other nit is that it utilizes a "dumb" type-c port, meaning that you must use the supplied USB type-a to type-c conversion cable, as it does not support PD over USB-C, but only 5v. It would not work with any usb-c PD charger (e.g. a macbook or samsung).Overall, a great bang for the buck, you can see and feel the looks and quality of a premium $130 helmet from this product. The company has good customer service if you have issues with the helmet and include a helmet guarantee where if you crash with one, you can exchange it for a new replacement, because they claim to prioritize your safety.I hope the American company is or becomes profitable and thrive. I'd like to see future premium additions such as "PD charging support", chime or BT/app indicator of activated light", camera attachment, modular peripheral support, etc. Wish I got in on the kickstarter but glad I pulled the trigger.Am now a fan of this product and curious to if others run into similar issues with sizing.

You don’t look ridiculous and the compact design is so modern and unique. On top of the comfort and feel the replacement guarantee if you’re ever in a accident they’ll replace the helmet free or charge!

This is a comfortable helmet, ideal for me when riding BayWheels, Divi and Citi bikes in various cities I travel to. It folds perfectly in my Fjallraven daypack, no more dangling helmet clipped to pack or holding it and leaving it behind :(. Lights are nice too and I have the green color so I feel super visible. Easy to open and close and adjust.

The product works well, but it would be even better if the price were reduced a bit.

I previously had a Plixi helmet for travel that is round in shape - so never really fit and it doesn't have a rear tightening knob. This one fits much better, but as the other reviewers say, order one size up. I tried a medium and it was too tight across the front of my head.Compared with the Plixi, this one creates a longer skinnier package when folded, but it's still going to fit in my carry on fine.The lights are a welcome extra but they feel loose in their mounts and are very hard to turn on - mostly because you are pressing a button at the back of the light against the helmet, but you feel like you should be pushing a button on the front of the light. On the Plixi, I had to order a glue on holder to hold a rear light, but not a front one.The Plixi has been around for a while, so there are more accessories. But their inner sweat pads are not as robust as the Fend'sI ordered the bright yellow and it's a good color.

Nice helmet but way to heavy. Twice as heavy as other helmets. I returned it.

Really neat design and very comfortable, but since these are rated for one time damage and have reports of the hinge mechanism failing after about a year, I couldn’t justify the cost. I returned for a traditional helmet.

I had the V1 and wore it all the time, but the fit wasn’t perfect. The V2 fit is perfect and building is high quality and comfortable to wear for long rides. The sides flaps lock securely so it feels safe.
