Not dorky, locks up, and she actually wears it — finally, a helmet my wife approves of.
My wife picked this helmet, and for the first time in history, she likes the way a safety device looks. It’s not dorky, it actually fits well, and the MIPS protection gives us peace of mind without looking like she strapped a spaceship to her head. Bonus points for the clever little hole to lock it up — makes leaving it on the bike feel way safer than the usual “hope no one swipes this” scenario. Comfortable, stylish-ish, functional, and actually used — exactly what a helmet should be. ... show more

Comfy and cute
This is a great helmet. I was looking for something MIPS rated since i had gotten a new ebike and am commuting in traffic. This helmet fits the bill. It’s comfy and cute. The color is as shown. The added light is a nice touch.

Lightweight, great fit
Color: Metro White Size: Medium
It was time to replace a Giro retro helmet with a fabric brim that had been discontinued. Tried the Retrospecs version but it was heavy, uncomfortable and hot. My head is kind of tall but a little flat in the back, so finding a good fit can be challenging. I got this helmet in a medium and it adjusts to the best fit ever for me. The strap adjustment clips on the sides snap open easily but close securely. The quick magnetic chin clasp is a nice touch. The dial adjustment on the back locks securely. Plenty of ventilation for commute/casual recreation. And it's cute! ... show more

Great helmet
Color: Club Navy Size: Medium
Love this helmet. It is comfortable to wear, well vented. Beautiful and sturdy. I am a small body frame person and the weight was ok. The magnet clip is easy to operate and convenient. My only issue is the charge life on the magnet light is not very long and I have yet to figure out how to get it to flash so the life can be extended. I would definitely buy it again. ... show more

Great helmet, saved my face
Color: Club Navy Size: Large
I'm new to biking and know nothing about helmets and really got lucky purchasing this one. It's light-weight, good looking (not space age chic, I'm 64 and just wanted something not too flashy), easy to get on and off (with the magnetic clasp), easy to adjust and has that great little hole for locking it up with your bike lock. I face planted the other day. Hard enough to break the visor. (Replacements are available on their website, but not on Amazon). It saved my face. I have some minor scrapes and scratches but with the visor shattering, I would have had a very different story to tell if I had not been wearing this helmet. I forget I have it on, it's so comfortable. I cannot recommend this helmet highly enough. And thank you Thousand, for saving my face! ... show more

Do NOT size down if your head is a “long oval” shape
** 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! ... show more

Stylish and Comfortable Helmet.
Color: Metro White Size: Small
Bought this helmet for my wife (e-bike rider). She wanted something comfortable, stylish and easy to adjust. This helmet works well for these goals. She said it fits well and the strap is easy to adjust. Love the magnetic buckle. The helmet is also surprisingly lightweight given the mostly solid shell. Well worth the price. ... show more
