Those construction worker vests can get real hot. I've never been dissatisfied with anything I've purchased from PI, and I've purchased a lot from them. I have a couple Canari hi viz jackets too, and I'm not real happy with them because they don't breathe very well, and when I take them off after a long ride, they're usually dripping wet. My favorite jacket is a vagabond PI product where I can zip off the sleeves. I'm lucky because there is a PI outlet store nearby and I usually get PI products at about 1/3 retail price. My wife also likes her various PI jackets, but her favorite is her Goretex wind$topper. I have to admit, it is a beautiful jacket.
