no has done a review on this yet so I'll give it a wack.
First of all the overall design is very good, but The fit is huge. You'll notice on the spotlight that the tester is 6' 4" and it fits him well. The spotlight on this is actually spot-on, except the weight.
My large weighed 9.1oz but fits like an XL. I think I got a heavy one because prolite gear had theirs weigh in at 7.8. This is not a bad thing, even though Golite claims 6oz, going one size smaller may get you in that range.
In the field the jacket works 1-10 a 6. As far as strength goes, a 5, but this is based on an accessment of other water-proof jackets I have seen or used. I would be more afraid of ripping this jacket than some of the ripstops because the fabric is flat and will have a better possiblity of ripping if it catches on something. It blocks wind very well but in less windy conditions you get a little clammy. I can't wait to try out the Reed pants since the lower body doesn't get all that clammy.
All in all, its a good way to get light weight rain gear at a good price.
I'm betting that someone will come along with a fabric that is lighter and more breathable in the next few years, but will probably cost a ton more.
So if your into the newest lightest gear that will do the job for backpacking, I would highly recommended it unless you do all of your hiking in the summer in the deep south.
