I live in the south and ride *a lot*. But there is no reason to replace my helmet just because I've ridden and sweated so much that my pads have come apart. By purchasing these replacements, I've been able to avoid buying a new helmet—I don't need one yet, and I love my Windmax helmet.
In addition to the regular-size pads, the package includes thick ones too. Plus, they throw in some Velcro-like hook stickers in case the ones inside your helmet no longer adhere. Thanks, Rudy Project. I needed those!
My only complaint is that they don't seem to last a long as the ones that came with the helmet. (and thus the four stars)
I suggest purchasing two packs at a time. The shipping is the same whether you buy one or two, and then you don't have to order more the next time you need them.
