Re: Any experience, good or bad with Phoenix pants
I have Pheonix pants (and jacket) for the same usage you plan. Over jeans and long sleeves for cooler weather. Over shorts and t shirt in the FL heat.
Luckily I haven't tested mine yet, but have read a lot of reports that indicate they are relatively good for that one crash - then replace them. For the money, and the fact that they are really comfortable in extreme heat (read you won't have an excuse not to wear them) as long as you are moving.
Be sure to get the tightest fitting size you can be comfortable in. Because the mesh gives more than leather, you want to keep the armor in place if you go down. My pants fit good everywhere except being too baggy around the hips. It's not as bad with jeans under them, but with thin shorts, I feel like the hip padding will be anywhere but over my hips after I hit.
If you live where it's hot, a mesh outfit is worthwhile whether it's Joe Rocket, FirstGear, Field Sheer, or whatever. It won't protect you like leather, but it's way ahead of no gear.
