Is there enough difference in the two helmets to justify paying $40 more for the Atmos (assuming both fit me)? They seem to be practically the same helmet.
Back when I was actively searching for a helmet, I tried both the Sweep and Atmos. The Sweep didn't fit my head quite right...it felt like it was sitting "on top" of my head, a very shallow fit IMO. The Atmos feels more like my head fits "into" the helmet...just fits my head better, so I went with the Atmos and have no regrets at all. But if both helmets fit your head exactly the same, then I'd say to go with the less expensive one...if price is a factor for you.
I was thinking of these two, but neither fit my head quite right...I went with the Specialized S-Works and couldn't be happier, so light and comfy! Head never feels hot either!
sorry, realized i didn't answer your question at all! I did end up paying only $120 for mine though!
Its all about fit. I got the Sweep because medium fit me like a glove. I seemed to be between sizes in the Atmos. They're both great all-around helmets.
