I'm really picky with my jackets and will quickly sell off gear that I fall out of love with such as these gems
Joe Rocket Phoenix mesh jackets
These (I have owned both) are really crappy and from what I have seen provide very little protection. If you are concerned about staying cool first and staying protected last then by all means have at it. It will literally shred on a 40 mph "off-bike excursion" and melt at any speed higher than that.
Fieldsheer Corsair. Much better and much more substantial than the Joe Rocket jacket. I wore this off and on for 2 seasons and it had pros but too many cons
Semi breathable without the liner, cooler than perforated leather
Springy/stretchy material, supposedly as strong as leather. Never put it to the test tho
Surprisingly warm with the liner in. You can wear this in 45 degree weather with just a t-shirt underneath
Waterproof with the liner in
Cheesy armour that moves about if you are not careful because there aren't any pockets
Standard back protector was a cheap foam pad. I've seen better padding in exercise mats.
Weak velcro. The sleeve velcro would invariably unfasten mid-ride
Liner does not breathe so on cool days you end up basting in your own sweat
But the biggest con for me was it would always be second best to Dainese Horizon jacket which a buddy of mine picket up and let me try out
Now this jacket hits the marks that the Fieldsheer misses. While they look similar they are different. The Dainese is a heavier jacket, isn't as stretchy but provides a better fit and feel. The armour is more substantial with none of the velcro worries and the liner is better thought out as well. Even the black is...well..blacker. And of course it can zip to dainese leather pants. I'm very pro-leather so for me to even consider a non-leather jacket at this point means that it has to be exceptional. This will be my next (and only) non-leather jacket.
