i've tried a lot of bike clothing and pretty much decided that pearl izumi makes the best bike stuff, so when I decided it was time to get an obnoxious yellow jacket, the vagabond II was a no brainer. When it arrived, the color was a perfect blinding yellow and the zip off sleeve unit was a brilliant design.
In riding with it a few times, I discovered several fatal flaws. 1-it doesn't breath worth anything, like wearing a plastic bag. 2-the elastic on the sleeves aren't very tight, so if it is cold out, you get a blast of cold air up the sleeves of your wind breaker--fail. 3-the stitching holding the sleeve zipper is not very strong and broke when trying to remove the jacket when it is all sticky and wet from problem #1
Overall, looks cool. Has some great features. If you don't sweat this is the jacket for you.

i wrote a longer review, but it got deleted through the login process, so here is the summary.
good:
1 - color is perfect
2 - zip off sleeve is a brilliant design (comes off in one piece)
bad:
1 - does not breath, like wearing a plastic bag
2 - the elastic at the wrist is not tight enough, allowing a freezing cold breeze up the sleeve of your windbreaker--fail.
3 - stitching holding on sleeve is not so strong and tears when you try and take of wet, sticky, sweaty jacket because of the first problem.

I ended up with a gore bikewear jacket. it was a little more dough, but addresses all the problems of this jacket.

We bike and hike in Joshua Tree National Park. This jacket is the greatest. When it's cool in the morning we wear it with sleeves, then when it warms up, off come the sleeves. They work like a charm, easy on and off. A well made, comfortable jacket. I'm a convert
