^^ the JtG staprest is fairly lightweight, it's actually made for a great summer trouser as it's very wearable in the heat, despite its typical poly/cotton fabric which all staprest are made from.  As far as quality....considering how much I've worn them without issue I guess the quality is good, but it's not like they're "internet mens forum" caliber quality.

I tried some, and I have to say I returned them straight away. Very very slim (and I'm by no means weighty), and the material mix had a strange shine to it almost like tracksuit bottoms. Worse still the ones I had, the seams were unstitching already, as if an above average (or even just average) sized guy had tried them and got stuck.

Not for me at all, but each to their own.
