FEND One Foldable Bike Helmet - Adult Mens and Womens Bike Helmet - Collapsible by 50% of Original Size - Safety Certified for Bicycle Road Bike Scooter Cycling Commuter Helmet

Works great and folds easily. Allows me to carry helmet in my back pack. Great when you use rental bikes (Lyft bikes) all the time.

I love the build quality and the design, and how it folds to fit in my rear-mounted bike bag when I'm not wearing it. Only two issues you should be aware of. 1. You can't fold both sides in simultaneously; they catch on each other, so you have to do one side at a time -- there's not enough tolerance between them. At first I thought it was a defect, but I'm pretty sure that's how they designed it. 2. Their larger size helmet still isn't that large -- if you have a larger head (I do), it may not fit comfortably.

Love the concept but for some reason the front part (which is padded) of helmet hurts my forehead & leaves a dent.

My daughter wanted a cool helmet so I got her this one. Now she thinks I am the coolest dad. I also installed an optional Bluetooth walkie-talkie inside of the helmet to help us communicate when we go on bike and scooter rides. I love the smile this brought to her face.

I bought this helmet specifically for the folding feature and its safety certification and it is amazing! The attention to detail is great it came in beautiful packaging and the design is well thought out. I commute in NYC every day and the helmet effortlessly folds and fits into my bag. It is compact while also being very comfortable. It feels more durable than then other folding helmet I have tried it locks into place when I unfold it and stays in place. Most importantly it is CPSC & CE Certified so I know it will keep me safe. The additional thick pads, canvas carrying bag, and rotating adjuster in the back are great touches. I couldn't be happier!
