Hi Candy,
Thanks again for sharing your feedback, we really appreciate customers like you! :)
Kristen
I like it. Thanks
Bought this model because the course I am on uses them. Helmet is black rather than yellow. Only caveat is the sticker on the back looks like it should be removable but isn't - I ended up using Sticky Stuff to get it off.
Good quality
Very comfortable highly recommend it
Good bright colour, good fit.
I bought this helmet after trying several on for size, weight etc. This vibrant colour makes me feel confident that I can be seen especially combined with the additional add on light.
Good fit. Love the bright colour.
Great fit and top value
I didn't take enough time sitting in the store with the helmet on and unfortunately on my first ride I developed a headache within 20 minutes. I tried to return the helmet the day after I bought it, to demonstrate that I only wore it for a very short time, as I saw another customer was allowed to return his but I was refused. the policy has changed and bicycle helmets cannot be returned for poor fit since they are safety equipment. Fair enough. Basically unless your head is oval shaped like the helmet then you shouldn't buy it as the adjustment only makes the space for your head more oval. Really, I'd recommend helmets with a fully adjustable inner plastic cage unless you've spent enough time in the store with it on to be sure it suits the shape of your head. I rushed this purchase and regret it, fortunately it's not too dear a lesson learnt.

Visible which is the main priority and can clip flashing rechargeable light at the back of the helmet
Unfortunately I feel I picked badly in choosing this helmet . I have worn it twice and each time it seems to be pressing on my skull and gives me a headache. I have never experienced this with any other helmet. There is limited padding on the inside compared to other helmets.
If you find the helmet uncomfortable, please return it to store with your receipt for an exchange.
regards,

Sizes
If you're between sizes, choose the bigger size.Choosing the right-sized helmet and getting the fit right is essential. For kids, never buy a helmet that is too big on the assumption that they will grow.M: 20.9” – 22.8”L: 22” – 24”
