    ** INITIAL REVIEW: 2 stars ** (Scroll down to see update.)

    This helmet is gorgeous and incredibly lightweight, but the advice to size down if you’re on the cusp was 100% wrong for my head shape.

    My head is 57cm or hat size 7 1/8, and is a “long oval” shape, which means long front to back and narrow side to side. I wear:
    - a large in women’s hats
    - a medium in men’s hats
    - a medium in most bike helmets (Giro, Bell, etc.)
    - a medium in most motorcycle helmets (Shoei, Arai, etc.)

    (FWIW, the size medium in the Nutcase Street helmet — a competitor that a lot of people try before shelling out for this Chapter helmet — is too tight on me, and the large is comically big. That helmet just doesn’t work for me at all.)

    57 cm is on the cusp between small and medium in most helmets, including this one by Thousand. So following their fit advice as well as that of other reviewers — and against my own better judgment — I sized down to a small in this Chapter helmet.

    Bad move. :( It pinches my head front to back. Awful pressure points; immediately headache-inducing.

    It’s a beautiful helmet, but I’m annoyed at the misguided advice to size down. Now I need to exchange it for a different size. Will update my review pending a response from Thousand customer service.

    ** UPDATE, two weeks later: 5 stars **

    Thousand customer service was great. They sent me a medium right from their warehouse in California, and it fits perfectly! Shipping was free. I returned the size small to Amazon.

    Now that the helmet fits correctly, I’ve explored all the accessories that come in the box.

    Based on other reviews, I think Thousand has fixed the issue with the magnetic USB tail-light turning on while charging. While I charged mine, only one small LED gently flickered (and then held steady when the charge was full). It certainly wasn’t blinking at full brightness while charging, like reviewers from previous years mentioned.

    The light does automatically turn on when it magnetically snaps on your helmet. And holy cow is it BRIGHT. I can see how this would be really useful in many cases but annoying in others.

    I love the pop-lock feature and can easily fit my U-lock through it.

    I’m convinced that, with MIPS, this is the best helmet on the market. It’s SO pretty and lightweight, it looks cool, it’s super functional, and I love the company’s free replacement policy. I love this helmet!

    LOVE this bike helmet. Fits extremely well, is light, attractive and MIPS rated. There is a place to attach the helmet to your bike chain lock so you don't have to carry the darn thing around AND a magnetic light that you can attach to your helmet or to your bike. Well made. Would buy it again in a minute!

    This is my first helmet in a while. I’m very pleased with the look, the shape, and how easy it was to customize. No more deciding which pads will work. I was unhappy with the shipping, thou. I ordered on Tuesday, the confirmation said Thursday, my birthday, then changed to Sunday, then Monday. I finally received it Monday. Good thing I’m pleased with the helmet.

    I used this helmet for a year. It is very comfortable, durable. Overall no complains but there are two small cons that I don't like:
    1. Secret poplock magnet is a bit weak, so sometimes if you shake hard it might fall off, fortunately it is tied to helmet, so you wont lose it. I recommend to tape it from the inside to the helmet if you don't use it so it wont bother you.
    2. You need to charge magnetic light more often than other bike lights. Also it is loose battery even if it is turned off (I don't know why, maybe I have defective one). Because of that I never can be sure that it is charged or charged enough for the bike trip. If you don't use it daily, always charge it to full before your bike trip because it probably loose it's charge during idle time.
    3. Price is a bit high...

    I’d read several reviews where customers were not satisfied with the fit but I decided I’d order the helmet and try. I’m very happy to report that the helmet fits me perfectly and was precise in the measurement. My head size is exactly at the high end of size “small” so I wasn’t Sure if I should size up but the size small is snug and not too tight. A few minutes fiddling with the straps and dial adjustment to get my exact fit and I’m off for a ride!

    2.0 out of 5 stars poor quality light
    Reviewed in the United Kingdom on February 12, 2025
    Color: Supermoon WhiteSize: LargeVerified Purchase
    The magnetic light for the back is poor quality. First, it has a micro-usb connection. For the price paid for the helmet, i'd expect a USB-C connection. In fact, i'd rather have that than a lot of the useless packaging which comes with the helmet (I don't need a cloth bag for it or a bike bracket for the light). Also, the light flashes as it's being charged which is an annoying flaw. It just means it will take longer to charge and it's flashing at a time not needed.
