I have 2 types of those jackets (with nice cuffs and w/o). And I also have the pants.

They are a very soft tyvek. They feel nice on the skin. Nice lightweight. The seams haven’t leaked on me yet in a steady rain. But I have not used them in a downpour yet.

However, for me, they don’t breathe well at all. I would not wear them above 60F. With any backpacking, I start sweating in them.

I breath much better in my O2 jacket. I also have driducks that I bought from GG. I would rate them close to the O2 but not as good in terms of breathability.

Sometimes I backpack w/ a one dollar 2oz poncho; still I use the O2 the most.

All in all, I use Yankz for non-backpacking in 50-60F weather. It’s a neat jacket with a statement to it (whatever that is <img src="/forums/images/graemlins/smile.gif" alt="" />).
