I have the O2 pants, they're great too! One issue I had was the leg is too bulky and can get caught in the chain, so you need to use a ankle strap to prevent getting them ripped on the chain-ring.

I've had the jacket and pants for many year, at least 5 years, and they are just starting to break down. I will happily buy them again. As you can see from the Almanzo pic, I put this gear through hell, and it comes back asking for more.
