I have old husky's sip 5.1 6.1 hi-flex and a pair of pfanners and the pfanners are by far superior. They are all hot but I've worn all pairs in up to 85 degree heat with ohio river valley humidity (bad but not deep south or tropics by any means) and the pfanners were the "coolest". Again they are all pricey but what is more expensive? 300-400 dollar pants that last couple years or not being able to do tree work for at least a couple of weeks up to forever? Cheap insurance imo.
