I have the Phoenix, and I happen to live in Phoenix... Perhaps there is a connection since it is pretty much the only jacket bearable in the summer here... and nothing is really bearable, but sometimes you gotta just sack up and ride anyway.
So here is my take, for future buyers. I agree, the arm straps are bullsh*t. They only have 2 snap options and the tightest is still too loose, and I tried on a large and it wasn't nearly long enough for my arms and waist. I should have probably been more discerning at the point of sale but I was all caught up in the light mesh and breathability.
Anyway, other thing is that the jacket is cut loose all around, the waist will fit and the length will fit, but then the bulk around the chest and the bulk in the arms makes me concerned that should I need that nicely placed armor anywhere in the jacket, it would simply roll away so quickly to expose joints and bones that I don't think there would be much of a point in having worn a jacket at all. THat mesh is hardly protection of any kind.
So my ultimate review, this jacket is designed for those who really want to wear nothing but their conscience is eased by wearing something that masquerades as protection when in actuality it most likely will offer very little.
