Question: sizing?
Document: love it fits great sizing was as described on their website. Check to see if it corresponds accordingly for you.
I usually wear an XL, but got this helmet in an XXL according to the Bern sizing chart. A little snug still, but i have a lot of hair. I love this helmet!
Overlooked the sizing recommendations and helmet was too small. Return and response from seller was excellent. Helmet a bit tight even in X-Large but over a few uses the foam liner, etc. conformed and now comfortable and secure.
So we ordered the Large based on the sizing given online and the reviews. However, its extremely tight on my husbands head. I think a XL or XXL would be a lot better. If you have a larger head I suggest sizing up.
Called the vendor for sizing before I purchased this helmet. Spoke to one of their customer service guys who was very knowledgeable, friendly and helpful. Helmet arrived on time. My husband loves it! would definitely purchase again and recommend this vendor!
A sturdy and stylish helmet. It matches the info on sizing. Quick delivery. Im satisfied! I can only recommend it if you don't want to look dumb in a bike helmet, but still want to enjoy riding with your head protected.
I have a real melon head and no helmet I have found to this point has fit properly. From the online description and sizing guidelines and fit comments I took a chance. This helmet fits perfectly and is great for bike trips!
it would be best to choose one size larger than the recommended size based on measuring your head.if you choose a smaller size or the correct fit and you grow your hair. Your start to get headaches and really tight fit.the product itself is good. just be careful with the sizing
Lightweight and comfortable. Love the visor and it has the capability of being &#34;winterized&#34;  I bought the large, which was the size that falls within the measurement of my head, and it just fits. If you are at the top end of the sizing reccomendation you might go one size larger. Fast delivery.
I've never had a bike helmet that I actually enjoy putting on my head, and I've owned many, but I honestly look forward to putting this on before riding. In terms of sizing, definitely go up. I'm a female with what I think is a somewhat small head, and the medium fits great.
