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 havenít leaked on me yet in a steady rain. But I have not used them in a downpour yet.
However, for me, they donít 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. Itís a neat jacket with a statement to it (whatever that is <img src="/forums/images/graemlins/smile.gif" alt="" />).
Thanks for the replies, everyone.
And Barry, sounds like these could work for me as all they'd be used for is rain protection at camp (don't need hiking protection as my mode of travel is via kayak) and as a vapor barrier liner in my sleeping bag. And I don't need bomber rain protection as I retreat to my tent when it starts raining really hard.
Do these things tend to attract dirt and get grungy looking fast? Any other comments would be appreciated.
