I bike commute to work and have been thinking of switching to a folding helmet for a few years now. I backed a crowdfunded folding helmet 2 years ago, but since it still hasn't shipped I figured I would check out the Fend. I liked it so much I bought one for my wife a month later!
VERY easy to fold up, fits more easily in my backpack folded, very comfortable, easy to adjust. Frankly, a really nice appearance as well, not too "roadie/sportie" but sort of pleasantly sophisticated.
Love this helmet.

Best helmet ever. Looks great, beautiful design, comfortable, plenty ventilation and the collapsable feature is super convenient but the helmet looks so good, I just want to keep it on!

I'm loving my new helmet. It feels very sturdy and durable, collapses to a width I can fit in my backpack, and looks sleek. It's also very breathable and sizing can be adjusted easily if I want to wear a hat underneath for shade. It also comes with some nice padding to fill out the sides. I have an XL dome and the M/L was good for me, with a little side padding needed. Very comfortable. Highly recommended!

This helmet is foldable, good design, and sturdy. It is suitable for driving an electric scooter. I like this!

Recently bought an E-bike and i wanted a helmet that wouldn't look weird on me and one that would fit easily into my back-pack. Saw this Fend helmet ad on Facebook, bought it here, and it did not disappoint. Comfortable snug fit, easily adjustable and it folds down so it fits into my back pack with no problems leaving plenty of room for other things i carry daily. Great product.
